Create an AI-Powered Social Media Campaign

Use AI and Canva to design branded social media graphics for any event.

Introduction

30 Second Summary

You have an event to promote, a project to share, or a community to grow. But every time you sit down to create a social media post, you stare at a blank canvas, juggle three different platforms, and spend hours trying to make something that looks halfway professional.

In this project, you will use AI to write compelling, platform-specific copy and define a visual brand identity. Then you will design polished social media graphics in Canva and export publish-ready assets for LinkedIn and Instagram.

What You'll Build

You will create a professional social media post promoting an event, complete with branded graphics, AI-generated captions, and accessibility-ready alt text. When you finish, you will have everything you need to hit publish on LinkedIn and Instagram.

By the end of this project, you'll have:

Professional, platform-ready graphics exported at the correct dimensions for LinkedIn and Instagram, with polished captions and alt text ready to post.
A reusable AI brand prompt that defines your colors, fonts, tone, and visual style so every future post looks like it belongs to the same brand.
A repeatable AI-assisted content workflow you can use for any future event, portfolio project, product launch, or community announcement.
Secret Mission: Build an AI Social Media Assistant that transforms any event into a complete, branded multi-platform campaign from a single master prompt.

Are there any prerequisites?

You need a free Canva account (canva.com) and access to an AI assistant like Claude or ChatGPT. No design experience or paid subscriptions are required.

Before We Start

Before we dive in, let's lock in what you're about to create and why it matters. Knowing your event and audience shapes every design decision and piece of copy you'll write.

Set Up Your AI Design Workspace

Before you write a single word of copy or place a single element on a canvas, you need your two core tools open and talking to each other: a design tool for building graphics, and an AI assistant for brainstorming and writing.

In this step, you'll confirm both tools are working, upload any assets you already have, and enter your event brief into the AI conversation so it has context for everything that follows.

In this step, get ready to:

Confirm Canva is ready with the Custom size button visible on the homepage.
Set up your AI assistant and enter your event brief as a reference.

Log in to Canva and upload your assets

Your design tool is where your brand identity and social media graphics come to life. Canva is a browser-based design platform with a free tier that covers everything you need for this project.

Open a new browser tab and navigate to canva.com.
Log in with your free Canva account.
Confirm you can see the Canva homepage with the Custom size button on the homepage banner.

You should see the Canva homepage with your recent designs (if any) and the Custom size option visible on the banner area at the top.

What is Custom size?

The Custom size button lets you create a design with exact pixel dimensions instead of picking from a template. You'll use it in a later step to create graphics at the precise dimensions each social media platform requires.

If you have any event photos, logos, or brand assets you want to use, upload them now by clicking Uploads in the left sidebar.
Drag your files into the upload area, or click Upload files to browse your computer.

No assets yet? No problem

Uploading existing assets is optional. If you do not have logos or photos ready, you can use Canva's free graphics library later when you build your design.

Don't see Custom size on the banner?

The Custom size button appears on the homepage banner when you are on the main Canva homepage. If you landed inside a design or a different page, click Home in the top-left corner to return to the homepage.

Set up your AI assistant with your event brief

Your AI assistant will brainstorm copy, refine your messaging, define your brand identity, and generate alt text throughout this project. You need it open in a separate tab so you can switch between it and Canva easily.

Open a new browser tab and navigate to claude.ai (if using Claude) or chatgpt.com (if using ChatGPT).
Log in with your existing account.
Send a quick test message (something simple like "Hello, are you ready to help me create a social media campaign?") to confirm your AI assistant is responding.

You should see a conversational response from the AI within a few seconds.

Not getting a response?

If your AI assistant is not responding, check that you are logged in and that your subscription or free credits are active. Try refreshing the page and sending the message again.

help me troubleshoot why my AI assistant is not responding

Now that your AI assistant is working, give it context about your event so it can help you throughout the project.

Type your event brief into the conversation. Include: what the event or announcement is, who it is for, when and where it happens, and what makes it worth attending.
Aim for 2-3 sentences that capture the essentials.

What makes a good event brief?

A strong brief answers four questions in 2-3 sentences: What is happening? Who is it for? When and where? Why should someone care?

For example: "I'm hosting a Build & Brew session for early-career cloud learners on Saturday August 16th at a local cafe in Melbourne. It's a casual, hands-on session where attendees build a real cloud project while networking with other builders."

Keep this brief in your AI conversation. It becomes your reference point for every prompt you write in the next steps.

Before moving on, confirm you have all three pieces in place: the Canva homepage with Custom size visible, a working AI conversation that responded to your test message, and your event brief saved in that conversation.

Your workspace is ready. Next up, you'll use your AI assistant to write compelling, platform-specific captions for LinkedIn and Instagram.

Write Professional Social Copy with AI

Your workspace is set up and your event brief is ready to go. Now comes the content that will actually live on your posts.

Writing platform-specific copy from scratch is time-consuming, especially when each platform has different conventions and audiences. Your AI assistant can draft multiple versions in seconds, giving you a strong starting point to refine rather than a blank page to fill.

In this step, get ready to:

Generate LinkedIn and Instagram captions from your event brief.
Iterate on tone, hooks, and length until the copy sounds like you.
Write alt text and collect relevant hashtags for your graphic.

Prompt your AI for platform-specific captions

A LinkedIn audience expects professional tone and clear value propositions. An Instagram audience responds to punchy, visual-first messaging with personality. Writing one generic caption for both platforms wastes the strengths of each.

Switch to your AI assistant tab where your event brief is saved.
Send a new message asking it to generate two captions based on your event brief. Tell it who your audience is and what action you want people to take (register, attend, share, etc.).
For the LinkedIn caption, specify: professional tone, 1-3 short paragraphs, and a clear call to action at the end.
For the Instagram caption, specify: punchy and conversational tone, use line breaks for readability, and include 3-5 relevant hashtags.
Send the prompt and review the two captions the AI generates.

You should see two distinct captions in the AI response. The LinkedIn version reads like a professional announcement, and the Instagram version feels more casual and scannable.

Why write for each platform separately?

Each social platform has different reading behaviors. LinkedIn users read longer professional posts in their feed, while Instagram users scan images in under 2 seconds and only tap to read captions if the visual hooks them.

A single caption posted to both platforms ignores these differences. Telling the AI about each platform's conventions upfront saves you from reworking a generic draft later.

Getting generic or robotic captions?

Make sure your prompt includes your event brief, your specific audience, and the action you want people to take. Vague prompts produce vague results.

Try adding a sentence like "Write as if you are a community organizer who is genuinely excited about this event" to inject more personality.

help me write a better prompt to get platform-specific social media captions that sound human

Iterate and refine your copy

First drafts from AI are starting points, not final copy. The real skill is knowing how to push back and steer the output toward something that sounds like you.

Read both captions aloud. Note anything that sounds stiff, overly formal, or unlike how you actually talk to your audience.
Send a follow-up message asking the AI to refine. Try asking it to adjust tone, shorten or lengthen a section, add urgency, swap the opening hook, or try a completely different angle.
Ask specifically for 2-3 alternative headline hooks for each platform. These give you options when you design your graphic later.
Keep prompting until you have versions that feel authentic. If a caption could have been written by anyone for any event, it needs more of your voice.

After a few rounds, you should have refined captions that feel specific to your event and audience. You should also have 2-3 headline hooks for each platform saved in the conversation.

Finding your voice in AI output

Try this test: if you showed the caption to a friend without context, would they guess you wrote it? If not, tell the AI what specifically feels off. Saying "make the tone more casual" is vague. Saying "I would never use the word 'synergy' unironically" gives the AI something concrete to work with.

Why iteration matters more than the first prompt

The gap between a first AI draft and your finished copy is where your taste and judgment live. Every refinement prompt teaches you what "good" sounds like for your brand. This iterative process is prompt engineering in practice.

Write alt text and collect hashtags

Your captions are ready, but you still need two more pieces before you move to design: alt text for accessibility and hashtags for discoverability.

Ask the AI to write alt text for the graphic you plan to design. Specify that it should be a concise, descriptive sentence under 125 characters that conveys the key information in the image for screen readers.
Tell the AI what visual elements you expect in the graphic (e.g., event title, date, a community illustration) so it can write alt text that matches your planned design.
Ask the AI to generate a short list of hashtags relevant to your event and audience. These should mix broad discovery hashtags with niche ones specific to your topic.
Review the alt text and confirm it is under 125 characters. If it is too long, ask the AI to shorten it while keeping the essential information.

What is alt text?

Alt text is a short written description attached to an image that screen readers read aloud for people who cannot see the image. It describes what the image shows so that everyone gets the same information, regardless of how they access your content.

Good alt text is specific and concise. "Promotional graphic for Build & Brew community session on August 15" is useful. "Image" or "social media post" is not.

Before you move on, take a moment to predict: do you have everything you need to start designing? Think about what a designer would ask for before opening their design tool.

Scroll through your AI conversation and confirm you have all of the following saved:

A polished LinkedIn caption (professional tone, 1-3 short paragraphs, clear call to action).
A polished Instagram caption (punchy, conversational, line breaks, 3-5 hashtags).
2-3 alternative headline hooks for each platform.
Alt text for your planned graphic (under 125 characters).
A short list of relevant hashtags.

If anything is missing, prompt the AI to generate it now. All of this copy stays in your conversation as your reference for the design steps ahead.

Alt text is over 125 characters?

Ask the AI to shorten it by removing adjectives and focusing only on the essential information: what the image shows and why it matters. Alt text does not need to be a complete sentence if a fragment conveys the meaning.

help me write concise alt text under 125 characters for my social media graphic

Your copy is locked in and ready to design around. Next up, you'll define a visual brand identity that ties all your content together and makes every future post instantly recognizable.

Create a Consistent Brand Identity

You have compelling captions and headline hooks ready to go. But if you design a graphic today with one color scheme and a different one next week, your audience will never recognize your content in a feed.

A defined brand identity solves this. It gives you a fixed set of rules (colors, fonts, tone, visual style) that make every post look like it belongs to the same person or community. In this step, you will use your AI assistant to define those rules and create a reusable prompt that keeps every future post consistent.

In this step, get ready to:

Define a color palette, font pairings, and tone of voice with AI.
Verify your color choices for accessibility (WCAG AA contrast).
Create a reusable AI brand prompt you can paste into any future conversation.

Define your visual identity with AI

Your AI assistant already knows your event and audience from the brief you wrote earlier. Now you will give it more context about your personality and style so it can suggest a visual identity that feels authentic.

Switch back to your Claude or ChatGPT conversation from earlier.
Send a prompt that includes: who you are or what your community is about (e.g., "I am a NextWork Build Master hosting Build & Brew sessions for early-career cloud learners"), your personality descriptors (energetic, calm, playful, professional, bold, minimal), and any existing brand elements you want to keep (a logo color, a font you already use, a style you admire).
In the same prompt, ask it to suggest a color palette with three colors: a primary color, an accent color, and a neutral or background color. Ask for hex codes for each.
Also ask it to suggest font pairings: one font for headlines and one for body text. Tell it to choose from fonts available on Canva Free (fonts without a crown icon in Canva's font menu).
Finally, ask it to write a one-sentence tone of voice statement that captures how your brand communicates (e.g., "Friendly and energetic, like a supportive teammate who makes complex topics feel approachable").

Your AI should respond with a complete set of suggestions: three colors with hex codes, two font names, and a tone statement.

What if I don't like the suggestions?

This is a starting point, not a final answer. Tell the AI what feels off. Say something like "The accent color is too muted, I want something more energetic" or "The headline font feels too corporate, suggest something friendlier." Iterate until the palette feels like you.

Choosing colors that feel right

If you are unsure where to start, tell the AI a mood or a reference. "I want the energy of a sunrise" or "Think of a cozy coffee shop with a modern twist" gives it something concrete to work from.

Check accessibility and define your visual style

A color palette that looks great on your screen might be unreadable for someone with low vision. Before you lock in your colors, you need to check that text will be legible against your backgrounds.

Send a follow-up prompt to your AI assistant. Provide your text color hex code and your background color hex code, and ask it to estimate the contrast ratio between them.
Tell it that WCAG AA requires at least 4.5:1 for normal text and 3:1 for large text. Ask if your combination passes.
If the AI says your contrast is insufficient, ask it to suggest an adjusted shade of your text or background color that passes while staying close to your original choice.

How accurate is AI contrast checking?

AI can approximate contrast ratios when given hex codes, but dedicated tools like WebAIM's contrast checker are more precise. For this project, the AI estimate is a practical first pass.

If you want to double-check later, paste your hex codes into a free online contrast checker.

Now define your image style. In the same conversation, tell the AI whether your graphics will use photography, illustrations, abstract shapes, or a mix. Describe what feels right for your brand.
Also define your spacing rules: do you prefer generous whitespace (clean and minimal), tight and bold layouts (energetic and packed), or minimal text on graphics (let the visuals speak)? Ask the AI to summarize your visual style direction in 2-3 sentences.

At this point, your AI conversation should contain your full brand identity: colors with hex codes, fonts, tone, visual style, and spacing preferences.

Create your reusable AI brand prompt

Every time you start a new AI conversation for a future post, you would need to re-explain your entire brand identity from scratch. A reusable brand prompt eliminates that. It is a single paragraph you paste at the start of any conversation that instantly gives the AI all the context it needs to stay on-brand.

Ask your AI assistant to consolidate everything into a "reusable brand prompt": a single paragraph that describes your brand colors (with hex codes), fonts, tone of voice, visual style, audience, and spacing preferences. Tell it this paragraph should work as a standalone briefing for any future AI conversation.
Review the brand prompt the AI generates. Make sure it includes all your key details and reads as a clear, self-contained instruction. Edit or ask the AI to refine it until you are satisfied.
Save this brand prompt somewhere permanent outside the conversation: a note-taking app, a pinned message, a text file, or a document you can easily find later.

Why save it outside the conversation?

AI conversations can get buried or deleted over time. Saving your brand prompt in a permanent location means you can paste it into any future conversation, with any AI tool, months from now. Think of it as your brand's instruction manual.

Now test it. Before you run this test, what do you think the AI will produce if you give it only the brand prompt and your event name?

Paste your saved brand prompt back into the AI conversation as if starting fresh. Then ask: "Based only on this brand prompt, describe what a social media post promoting my event would look like. Include colors, layout, text placement, and mood."
Review the AI's response. It should describe a design that matches your brand identity without needing any extra context from the earlier conversation.

If the description matches your vision, your brand prompt works. If something is off (wrong color emphasis, missing font reference, tone mismatch), update the prompt and test again.

AI description doesn't match your brand?

Check that your brand prompt explicitly names every detail: hex codes, font names, tone keywords, and visual style. Vague phrases like "modern colors" give the AI too much freedom. The more specific your prompt, the more consistent the output.

Help me fix my brand prompt

You now have a complete, documented brand identity and a reusable prompt that acts as your personal AI creative director. Every future post starts with this prompt, keeping your content instantly recognizable across platforms.

Your brand rules are locked in. Next up, you will bring them to life by designing a real LinkedIn post in Canva.

Design a LinkedIn Post in Canva

Your brand identity is locked in. You have hex codes, font pairings, a tone of voice, and a reusable AI prompt that keeps everything consistent.

Now it's time to put those rules to work. In this step, you'll design a LinkedIn post graphic in Canva at the optimal feed dimensions. This is where your brand stops being a document and becomes something people actually see in their feed.

In this step, get ready to:

Create a custom-size canvas at 1080 x 1350 px.
Build a branded layout with your headline, supporting text, and a visual element.
Verify your design passes an accessibility and quality checklist.

Create a custom-size canvas

LinkedIn's mobile feed displays portrait images at a 4:5 aspect ratio. A 1080 x 1350 px graphic takes up the maximum amount of screen space, making your post impossible to scroll past.

On the Canva homepage, click Custom size on the banner.
Set the unit to px.
Enter 1080 for Width.
Enter 1350 for Height.
Click Create new design to open the editor.

You should now see a blank white canvas in the Canva editor. The dimensions in the header bar read 1080 x 1350 px.

Why 1080 x 1350?

This is the 4:5 portrait ratio. It takes up the most vertical real estate in LinkedIn's mobile feed, which means your post dominates the screen and demands attention.

The same dimensions also work perfectly for Instagram feed posts, so you'll be able to reuse this canvas size in the next step.

Don't see Custom size?

Make sure you're on the Canva homepage (canva.com), not inside an existing design. The Custom size button appears on the homepage banner near the top of the page.

help me find the Custom size button on the Canva homepage

Build your branded layout

Your design needs to communicate one clear message at a glance. You'll build it in layers: background, headline, supporting text, then a visual element.

Click anywhere on the blank canvas to select it.
In the toolbar above the canvas, click the color swatch (the small colored square).
Click the hex code field at the top of the color picker and paste your primary or neutral brand color hex code.
Press Enter to apply the color.

Your canvas background should now be your brand color instead of white.

Click Text in the left sidebar.
Click Add a heading to place a text box on the canvas.
Replace the placeholder text with your strongest headline hook from Step 2.
Select the text, then use the font dropdown in the toolbar to change it to your headline font.
Set the font size to 40pt or larger using the size field next to the font dropdown.
Drag the text box to the upper third of the canvas for immediate visibility.

Your headline should now sit prominently in the upper portion of the design. This is the first thing someone sees when scrolling.

Why the upper third?

In a social media feed, your graphic competes with everything else on screen. Placing the headline high means it's visible even before someone scrolls the full image into view.

Click Text in the left sidebar again.
Click Add a subheading to add a second text box.
Replace the text with your supporting line: the date, time, or value proposition.
Change the font to your body font using the font dropdown.
Position it below the headline, leaving generous spacing between the two.

You now have two text layers. Keep your total text to a maximum of two lines. The graphic should communicate one clear message, not a paragraph.

Click Elements in the left sidebar.
Search for an illustration, icon, or shape relevant to your event.
Click a free element to add it to your canvas. Look for items without a crown icon (crown means Pro-only).
Resize and position your visual element to complement the text without competing with it.
If your element supports color changes, click it and use the color swatch in the toolbar to apply your accent brand color.

Use your own photo instead

If you uploaded event photos or brand assets to Canva earlier, click Uploads in the left sidebar to find them. A real photo often feels more authentic than stock illustrations.

Step back and look at your design. You should see a colored background, a bold headline in the upper third, a supporting line below it, and a visual element that adds interest without overwhelming the text.

Run the accessibility and quality checklist

A beautiful design that nobody can read is a wasted design. Before you move on, check your work against these accessibility and quality standards.

Color contrast between text and background meets WCAG AA (4.5:1 minimum for normal text, 3:1 for large text).
Text is at least 24pt for body copy and 36pt or larger for headlines (readable on phone screens).
All important content sits inside the safe zone (at least 100px from edges to survive cropping).
Total text on the graphic is under 20% of the canvas area (keeps it scannable).
The design uses only your brand colors (no random default colors left from Canva templates).
It passes the scroll test: would you stop scrolling to look at this?

What is the scroll test?

Imagine your graphic appearing between two other posts in a busy LinkedIn feed. If it doesn't grab your attention in under 2 seconds, something needs to change. Common fixes: increase contrast, make the headline bigger, simplify the layout, or swap the color scheme for something bolder.

How do I check contrast without a dedicated tool?

You already verified contrast in Step 3 when you asked the AI to check your brand color hex codes. If you've changed any colors since then, switch to your AI tab and provide the updated hex codes. Ask it to confirm the contrast ratio still meets 4.5:1.

Fix any items that didn't pass the checklist. Adjust colors, increase font sizes, or reposition elements as needed.
Make sure all your edits still use your brand identity. No placeholder fonts or default blues.

Before you call this done, ask yourself: does this look like something I'd actually post? If the answer is yes, your LinkedIn graphic is ready.

Design doesn't feel professional?

The most common culprits are too many competing elements, inconsistent spacing, or text that's too small. Try removing one element, increasing whitespace between text layers, or bumping your headline font size up by 10pt.

help me improve my Canva design so it looks more polished and professional

Your LinkedIn graphic is done and looking sharp. Next up, you'll adapt this design for Instagram and export both versions as publish-ready files.

Adapt the Design for Instagram and Export

Your LinkedIn graphic is polished, accessible, and ready to post. Now it is time to bring the same message to Instagram.

Copying the LinkedIn design directly to Instagram will not work. LinkedIn designs tend to be text-heavy and professional. Instagram audiences expect visuals-first with minimal text. You need to redesign for the platform, not just resize.

In this step, get ready to:

Redesign your LinkedIn graphic for Instagram conventions.
Review both versions for brand consistency and accessibility.
Export both designs as publish-ready PNG files.

Duplicate your LinkedIn design for Instagram

Instagram and LinkedIn share the same 4:5 aspect ratio at 1080 x 1350 px. The dimensions are identical. The design language is not.

In your Canva editor, hover over the upper corner of your LinkedIn design page.
Click Duplicate page.

A new page appears as an exact copy of your LinkedIn design. Before you start editing it, take a moment to look at this duplicate.

If you posted this exact design on Instagram, do you think it would stop someone mid-scroll? What would an Instagram user think?

Why this duplicate does not work for Instagram

Instagram users scan images in under 2 seconds. A text-heavy LinkedIn layout with multiple lines of copy, a detailed value proposition, and a professional tone feels out of place in a feed dominated by bold visuals and minimal text.

The visual hierarchy needs to flip. On LinkedIn, text leads and visuals support. On Instagram, the visual leads and text takes a back seat.

Now redesign the duplicate for Instagram. Make the following changes to page 2:

Make your visual element (photo, illustration, or shape) larger and more prominent. It should dominate the canvas.
Reduce text to just your headline or a single punchy phrase. Remove supporting lines like date, time, or location from the graphic.
Move detailed information (date, time, location, event description) to the caption instead. Your Instagram caption from Step 2 already contains this.
Increase white space around elements so the design breathes.
Make sure any remaining text is large enough to read without tapping to expand (at least 36pt for headlines on Instagram).

What should I see?

Your Instagram page should look noticeably different from your LinkedIn page. The visual element is dominant, there is very little text, and the overall feel is bolder and simpler. The same brand colors and font family tie both pages together, but the layouts serve different audiences.

Scroll between page 1 and page 2 in the editor. You should immediately see the difference: page 1 is information-rich and professional, page 2 is visual-first and scannable.

Both pages look too similar?

If your Instagram version still feels text-heavy, try removing one more text element. The goal is that someone can understand the post without reading a single word. The visual and a single phrase should tell the story.

My Instagram design still looks too similar to my LinkedIn version. How can I make it more visuals-first?

Review both versions for brand consistency and accessibility

Both pages should feel like they belong to the same campaign. A viewer should recognize them as related without reading a word.

Scroll between both pages in the Canva editor and ask yourself these questions:
Do both designs use the same brand colors (primary, accent, neutral) from your brand identity?
Do both designs use the same font family (even if sizes differ)?
Does the Instagram version communicate its message without needing the caption?
Would someone scrolling a feed recognize these as part of the same campaign?

Now run the accessibility checklist on your Instagram version:

Verify color contrast between text and background meets WCAG AA (4.5:1 minimum for normal text, 3:1 for large text).
Confirm all text is at least 24pt for body and 36pt+ for headlines.
Check that all content sits inside the safe zone (at least 100px from edges).
Confirm your design uses only your brand colors with no leftover Canva defaults.

The scroll test

Ask yourself: if this appeared in my Instagram feed between two other posts, would I stop scrolling? If the answer is no, make the visual element bigger or the headline bolder.

Export both designs and organize your project

Both designs are finished. Time to export them as publish-ready PNG files and organize your Canva project for future use.

First, give each page a descriptive name so you can find them later:

Hover over the top corner of page 1 and click the Add page title field that appears.
Type LinkedIn Post and press Enter.
Do the same for page 2, naming it Instagram Post.

Now export page 1 (your LinkedIn graphic):

Click Share in the top-right corner of the editor.
Select Download.
In the file type dropdown, choose PNG.
Under page selection, choose Custom and select only page 1 (LinkedIn Post).
Click Download.

Now export page 2 (your Instagram graphic):

Click Share in the top-right corner again.
Select Download.
Choose PNG as the file type.
Under page selection, choose Custom and select only page 2 (Instagram Post).
Click Download.

Rename the downloaded files descriptively on your computer (for example, build-and-brew-linkedin-1080x1350.png and build-and-brew-instagram-1080x1350.png).

Why PNG and not JPG?

PNG renders text and logos more sharply than JPG because it uses lossless compression. Social media platforms compress your upload anyway, so starting with the highest-quality source file gives the best final result.

Before you call this done, do you think both files will be under 5 MB? At 1080 x 1350 px with standard PNG compression, they almost certainly will be.

Check each file's size in Finder (macOS) or File Explorer (Windows). Both should be well under 5 MB.

You now have two publish-ready social media graphics, each tailored to its platform, exported and ready to post.

File larger than 5 MB?

This is unlikely at 1080 x 1350 px, but if your design uses very high-resolution uploaded photos, the file might be larger. Re-export and check that you selected PNG (not PDF or SVG). You can also try removing a large background image and replacing it with a solid brand color.

Help me reduce my exported Canva PNG file size

Your AI-assisted social media campaign is complete. You have platform-specific graphics, polished captions, alt text, and a reusable brand system that makes every future post faster. Next up: a Secret Mission that turns this one-time workflow into a reusable AI Social Media Assistant.
