Create a Community Event Poster with AI

Use Adobe Express AI to design a print-ready community event poster.

Introduction

30 Second Summary

You have seen a stunning event poster online and thought, "I want something like that for my community." But opening a blank canvas and figuring out layout, fonts, and colors from scratch is where most people give up.

In this project, you will describe a poster style you admire to Adobe Express's AI template generator, which builds a professional layout for you in seconds. You will then swap in your own photos, remove their backgrounds with AI, add your event details, and export a finished poster for both printing and digital sharing.

What You'll Build

Picture handing someone a poster that looks like a professional designer made it, featuring real photos of people from your community blended seamlessly into a polished, AI-generated layout.

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

A community event poster where your reference design's style is recreated through an AI text prompt, not manual layout work.
Real photos of people with backgrounds cleanly removed using AI background removal, so they look designed into the poster.
Two export files: a print-ready PDF and a shareable PNG of your finished poster.
Secret Mission: Adapt your poster into a matching square Instagram flyer, rethinking layout and visual hierarchy for a phone screen.

Are there any prerequisites?

No prior design experience is needed. This project walks you through creating a free Adobe Express account and every step from there.

Before We Start

Before we dive in, let's lock in what you're about to build and why it matters to you.

Create Your Adobe Account and Find Your Inspiration

You have seen a poster design online that captures exactly what you want for your community event. The challenge is turning that inspiration into your own polished poster without starting from a blank canvas.

In this step, you will create your free Adobe Express account and study your reference poster's visual style. These two ingredients prepare you to describe the design to the AI template generator in the next step.

In this step, get ready to:

Create a free Adobe Express account.
Find and study a reference poster design.

Create your free Adobe Express account

Adobe Express is a free, web-based design tool. You need an account to access its AI template generator, which is the tool that will build your poster layout for you.

Open your browser and go to express.adobe.com.
Look for the free sign-up option on the page. You will see both a free trial button and a Get Adobe Express Free link.
Click Get Adobe Express Free to create a free account without a trial.
Create your account using your email, Google, or Apple ID. No credit card is required for the Free plan.
Once your account is created, sign in to Adobe Express.

What is Adobe Express?

Adobe Express is a browser-based design tool that includes an AI template generator. You describe the style you want, and it builds a complete poster layout with balanced composition, colors, and typography for you.

The Free plan covers everything you need for this project, including AI-powered template generation, background removal, photo editing, and PDF export.

You should now see the Adobe Express homepage. It shows templates, quick-create options, and a search bar for finding design assets.

Can't sign up or sign in?

If you already have an Adobe account (from Photoshop, Lightroom, or any other Adobe product), skip sign-up and sign in with your existing credentials. Your existing account works with Adobe Express.

If you are stuck on email verification, check your spam folder for the confirmation email from Adobe.

Find and study your reference poster

The AI template generator builds poster layouts from text descriptions. The more specific your description, the closer the result matches the look you want.

Think of a poster design you have seen online that you want to recreate. If you do not have one in mind, search for event posters on Pinterest or Google Images until you find a design that catches your eye.
Open your reference poster in another browser tab, or save the image to your device.

You will use these observations to write your AI prompt in the next step. Study your reference poster and note the following four things:

Study the color palette. Note whether the colors are warm, cool, bright, or muted.
Study the layout style. Note whether it is centered, asymmetric, photo-heavy, or text-heavy.
Identify the mood. Decide if it feels playful, elegant, bold, or minimal.
Check the typography style. Look for large bold headlines, handwritten fonts, or clean sans-serif text.

Why study a reference poster first?

Describing a design style to AI is harder than it sounds. A vague prompt like "make a nice poster" gives generic, unusable results.

When you note a reference poster's specific palette, layout, mood, and typography, you can feed those details directly into your prompt. The more concrete your description, the closer the AI gets to the look you want.

You now have two things ready: an Adobe Express account and a clear picture of the design style you want to recreate.

Next up, you will translate those observations into a text prompt and watch the AI template generator build a professional poster layout in seconds.

Generate a Poster Layout from a Text Prompt

Your Adobe Express account is set up and your reference poster's style is locked in. Now for the fun part: turning that inspiration into an actual poster layout.

Starting from a blank canvas is where most people get stuck, because you have to make dozens of layout decisions at once. Adobe Express's AI template generator handles those decisions for you based on a text prompt you write.

In this step, get ready to:

Write a detailed text prompt that describes your reference poster's style to the AI.
Generate poster templates and browse the AI's results.
Select a template that matches your vision and open it in the editor.

Write your prompt and generate poster templates

The four observations you made about your reference poster become the ingredients for your AI prompt. The more specific you are about mood, colors, and layout, the closer the AI gets to your vision.

Return to the Adobe Express homepage at express.adobe.com in your browser.
Search for Poster using the search bar at the top of the page.
Scroll down to the Generate Template section.
In the prompt field, type a description of the poster you want. Pull from the observations you noted about your reference poster: the color palette, mood, layout style, and event type.

Craft a specific prompt

Your prompt needs to be at least 5 words long. The more descriptive, the better.

Here is an example for a bright, playful block party poster: "bold and colorful community block party poster with large headline at the top, space for photos of people in the center, warm orange and yellow colors, playful and fun mood."

Swap in the details you noted about your own reference poster. Mention specific colors, the type of event, and the layout you want.

Before you click Generate, take a guess. How close do you think the AI will get to your reference poster's style from just a text description?

Click Generate.

Several poster template options appear based on your prompt. Each one interprets your description a little differently.

What just happened?

Adobe Express's AI template generator read your text prompt and built multiple complete poster layouts from scratch. Each template includes a headline, body text areas, image placeholders, a color scheme, and a balanced composition.

You did not have to decide where anything goes. The AI made those layout decisions based on the style you described.

Pick the template that matches your vision

Browse through the generated poster templates.
Compare each option to your reference poster's mood, color scheme, and layout style.
If none of the templates feel right, click Generate more results to see additional options.
If the results are still off, refine your description in the prompt field with different style words and click Generate again.
Once you find a template that captures the right feel, click on it to open it in the editor.

The template opens in the Adobe Express editor with a full poster layout ready to customize.

Templates not matching your reference style?

Try describing specific visual details instead of general moods. "Large white serif headline centered at the top with a dark blue background" works better than "elegant poster."
Switch back to your reference poster and note one detail you did not include in your prompt. Add it and regenerate.
If you have used several generations and want to save your remaining daily uses, pick the closest match and move on. You can always fine-tune the design manually in the editor.

Still stuck? Help me improve my AI prompt so the generated poster templates match my reference poster style.

Compare the AI layout to your reference poster

Switch to the browser tab with your reference poster, or pull up the saved image on your device.
Place it alongside the Adobe Express editor and compare the two designs side by side.

The AI built a complete poster layout with balanced composition, a coordinated color scheme, typography hierarchy, and placeholder imagery. The overall mood should feel similar to your reference poster.

The images, however, are generic stock photos. Your community is not in this poster yet. That is exactly what the next step fixes.

Why do the images matter so much?

A poster's layout and colors set the tone, but the photos are what make it feel personal. Right now, the AI gave you a professional shell filled with strangers. Swapping in your own photos is what turns this from a generic template into your community's poster.

Your poster layout is in place. Next up, you will swap those generic stock photos for your own real photos and make this poster truly yours.

Swap In Your Real Photos

Your poster layout looks polished, but every photo on it is a generic stock image. To make this poster actually represent your community, you need to swap those out for real photos of real people.

In this step, you'll replace the placeholder images with your own photos and position them within the layout. Have a few phone photos of people ready on your device.

In this step, get ready to:

Upload your own photos to replace the placeholder images.
Resize and reposition your photos to fit the layout.
Evaluate how the overall poster looks with your real photos in place.

Replace the placeholder images with your photos

Click on one of the placeholder images in your poster.
Look for a Replace option in the menu that appears.
If you don't see a Replace option, delete the placeholder image and use the media panel on the left to upload your own photo from your device.
Select a photo of a person from your community event, gathering, or any photo you'd like to feature on the poster.

Your photo now appears in the poster where the stock image used to be.

Repeat this process for any additional photo placeholders in your poster.

Pick photos with clear faces

Photos where the person is clearly visible and well-lit work best. Avoid distant group shots or blurry images since they lose detail when placed into a poster layout.

Resize and reposition your photos

Click on one of your uploaded photos to select it.
Drag the corner handles to resize the photo so it fills the space where the placeholder was.
Drag the photo to reposition it within the layout.
Use the alignment guides and snap points that the editor shows as you move elements around.
Repeat for each of your uploaded photos until they are all sized and placed where you want them.

Each photo should now sit roughly in the position the original placeholder occupied.

Photo looks stretched or cropped weirdly?

If your photo looks distorted, make sure you are dragging from a corner handle, not an edge handle. Corner handles keep the original proportions. Edge handles stretch the image in one direction.

Help me fix my photo sizing in Adobe Express.

Step back and look at the full poster

All of your real photos are now in the poster. Before you judge the result, predict: does your poster look more polished now with your real photos, or has something changed for the worse?

Look at the full poster now. Your photos carry their original backgrounds. A kitchen wall, a backyard, or a crowd of bystanders now visually competes with the poster's designed background.

The lighting and colors from your casual phone photos probably don't match the poster's palette either. The poster went from looking professionally designed to looking like a rushed collage.

Why do the photos look pasted on?

The AI-generated template was designed as a unified composition. Every element, from the background color to the lighting on the stock photos, was crafted to work together.

Your casual phone photos were taken in completely different environments with different lighting, colors, and backgrounds. Dropping them straight in breaks that visual unity. This is the single biggest challenge when combining real photos with designed templates.

Your photos are in the poster, but those clashing backgrounds are holding the whole design back. In the next step, you'll use AI-powered background removal to strip those backgrounds away and make your photos look like they belong.

Clean Up Your Photos with AI Background Removal

Your poster now has your real photos in place. The problem from the last step is still staring back at you: the backgrounds from your original photos are clashing with the poster's designed background.

Adobe Express has a one-click AI tool that removes photo backgrounds, isolating just the person on a transparent layer. You will use it to clean up each photo, adjust the colors to match the poster's palette, and position everything for a polished result.

In this step, get ready to:

Remove photo backgrounds with one-click AI background removal.
Adjust each photo's colors to blend with the poster's palette.
Reposition and resize your photos for a natural, designed look.

Remove the background from your photos

Right now, each photo carries its original background: a kitchen wall, a backyard, a crowd of bystanders. These backgrounds compete with the poster's designed look and make everything feel mismatched.

Click on one of your uploaded photos in the poster.
In the editing options that appear, find and click Remove Background.

The background disappears instantly. The person in your photo now sits directly on the poster's designed background with no clashing scenery behind them.

What just happened?

Adobe Express uses AI to detect the outline of the person in your photo and separate them from the background. The result is a transparent cutout that blends cleanly with whatever is behind it on the poster.

If the edges look a little rough around hair or clothing, you can use the Erase and Restore brush tools to refine the cutout. For most photos, the one-click result is clean enough to move on.

Now repeat this for each remaining photo in your poster. Click on the next photo and click Remove Background again.
After processing all your photos, check that every person sits cleanly on the poster's background with no original photo backgrounds remaining.

Don't see Remove Background?

Make sure you have clicked directly on the photo in your poster. The editing options only appear when a photo is selected.

If the option appears locked or asks you to upgrade, you can use Adobe's free standalone background remover instead. Go to adobe.com/express/feature/image/remove-background in your browser, upload your photo, download the transparent result, and then re-upload it into your poster project.

Help me find the Remove Background option in Adobe Express.

Adjust your photo colors to match the poster

Your photos now have transparent backgrounds, but the colors might still feel off. A photo taken in warm indoor lighting will look noticeably different from a poster with cool blue tones. Small color adjustments bridge that gap.

Click on one of your background-removed photos in the poster.
In the editing options, look for the Enhancements menu. This is where the color adjustment sliders live.
Use the sliders for brightness, contrast, saturation, and warmth to nudge the photo's colors closer to the poster's palette.

Which sliders should I adjust?

If your poster uses warm, saturated colors (oranges, yellows), increase warmth and saturation slightly on your photo.
If your poster uses cool, muted tones (blues, grays), reduce saturation and lower warmth on your photo.
Small adjustments go a long way. Move each slider a little, then look at the poster as a whole before adjusting further.

Repeat the color adjustments for each remaining photo. Click each photo and use the Enhancements sliders to match it to the poster's palette.

After adjusting, glance at the poster as a whole. The photos should feel like they belong in the same color world as the designed background and text.

Colors still feel off?

If the photo was taken in very different lighting (harsh flash, dim indoor light), no amount of slider adjustment will perfectly match the poster. Focus on getting close rather than perfect. The background removal already did the heavy lifting by eliminating the biggest visual clash.

Help me match my photo's colors to my poster design.

Reposition and resize for a natural blend

Your photos are cleaned up and color-matched. The final step is making sure they sit naturally in the layout, not floating awkwardly or overlapping important text.

Click on each cleaned-up photo and drag it into position within the poster layout.
Use the corner handles to resize the photo so it fills its space proportionally. The editor will show alignment guides when you get close to the center or edges.

Before you do a final comparison, think back to what the poster looked like at the end of the last step. Can you picture the difference between then and now?

Now compare your poster as it stands to how it looked when the photos still carried their original backgrounds. Your real photos should sit cleanly in the layout with no clashing backgrounds. The people in the photos look like they naturally belong in the design.

Photos still look pasted on?

Check that all backgrounds were fully removed. Click on each photo and look for any remaining background edges. If you spot leftover background, click Remove Background again or use the Erase brush to clean up the edges.

Also check the sizing. A photo that is too large or too small for its space will look out of place even with a perfect cutout. Resize until it feels proportional to the other poster elements.

Help me make my photos look more natural in the poster.

Your photos now look like they were part of the original design. Next up, you will add the real event details and download the finished poster for both printing and sharing.

Add Event Details and Download Your Poster

Your photos now sit cleanly inside the poster layout, with transparent backgrounds and color adjustments that make them look like part of the original design.

There is one big gap left. A beautiful poster with no event details is just wall art. In this step, you will replace the placeholder text with your real event information, set up a clear typography hierarchy so readers know what to look at first, and download the finished poster in two formats: a print-ready PDF and a shareable PNG.

In this step, get ready to:

Replace all placeholder text with your real event details.
Review the design for readability and alignment.
Download the poster as both a PDF and a PNG.

Replace the placeholder text with your event details

The AI template filled your poster with sample text like a generic event name and placeholder dates. Now you will swap in the real information so the poster actually tells people where to go and when.

Click on the main headline text in your poster (the largest text element).
Replace it with your event name. For example, type Greenville Community Block Party or whatever your event is called.
Click on the next text element and replace it with your date and time.
Click on any remaining text elements and replace them with your location and address, plus a contact detail or website.
If the template has a description area, write a brief 1-2 sentence invitation to the event.

Your poster now has real event details instead of placeholder text.

What is typography hierarchy?

Typography hierarchy is the way you use different text sizes and weights to guide the reader's eye. The most important information (your event name) should be the largest and boldest text on the poster. The date and location should be mid-size so they are easy to find. Any description text should be the smallest.

This size difference tells the reader what to look at first, second, and third, even from across a room.

Click on your event title and make sure it is the largest and boldest text on the poster. If it is not, select it and increase the font size in the editing panel.
Make sure your date and location text is clearly visible at a mid-size. It should be easy to read but smaller than the title.
If you have a description, make it the smallest text on the poster.

You should now see a clear size difference between your title, date/location, and description text.

Text too small or too large?

If your text overflows its text box or looks cramped, click on the text element and drag the handles to resize the box. You can also select the text and adjust the font size directly in the editing panel on the left side of the editor.

Help me adjust text size and positioning in my poster.

Review your design for readability and alignment

Before you download, do a final quality check. Small issues like text running off the edge or blending into the background will show up immediately on a printed poster.

Zoom out so you can see the entire poster at once.
Check that no text or photos are cut off near the edges of the poster. Leave a small margin of space around all edges.
Read each text element against the background behind it. If any text is hard to read, consider adding a text shadow or adjusting the text color for better contrast.
Use the alignment guides in the editor (they appear as lines when you drag elements) to keep everything tidy and centered.
Compare the finished poster to your reference design one final time.

Improve readability with shadows

If text is hard to read against a busy background, select the text box, go to Text in the left panel, then Effects. Choose a Shadow effect to add a subtle drop shadow that makes the text pop against the background without covering any part of your design.

Your poster should now look polished, with readable text and well-positioned photos.

Download your poster as PDF and PNG

Your poster is ready to leave the editor. You need two versions: a PDF for printing (at a print shop or at home) and a PNG for digital sharing (email, messaging apps, social media).

Click the Download button in the top right corner of the editor.
In the format options, select PDF.
Click Download to save the PDF to your device. This is your print-ready file.

Now download a second copy for digital sharing.

Click the Download button again in the top right corner.
This time, select PNG as the format.
Click Download to save the PNG to your device.

Why two different file formats?

PDF preserves the exact layout, fonts, and colors at full resolution. Print shops expect this format because it prints without quality loss at any size.

PNG is a high-quality image format that works everywhere online. It loads quickly in emails, messaging apps, and social media posts. Most digital platforms do not accept PDF uploads, so the PNG gives you universal shareability.

Before you check your Downloads folder, what two files do you expect to see there?

Open your Downloads folder in Finder (macOS) or File Explorer (Windows).
You should see two new files: a PDF and a PNG of your finished poster.

Don't see the Download button?

If the Download button is missing from the top right corner, try closing your browser tab and reopening the Adobe Express editor. A simple page refresh sometimes does not restore it.

If the download starts but you cannot find the file, check your browser's default download location. Most browsers save to the Downloads folder.
