A layout set for every photo count

Two photos get side-by-side and stacked, five get mosaics, nine gets the classic 3×3. The layout row redraws for however many photos you add, so a grid never ships with an empty hole.

Drag photos to swap, right on the canvas

Rearranging is not a settings menu. Grab a photo, drop it on another, they trade places — and Shuffle deals a fresh arrangement when you would rather not decide.

High-res export, no watermark

Download renders the collage at 2048 pixels as JPG or PNG with nothing stamped in the corner — and no sign-up wall standing in front of the button.

Blend the photos into one scene with AI

Beyond the grid: send up to four of your photos to Nano Banana 2 in Overchat and it merges them into a single seamless picture — the same subjects, one scene.

How to make a photo collage

1

Add up to 9 photos

Drop them onto the canvas, paste from the clipboard, or press Add photos. JPG, PNG, WebP and HEIC all work — or press Use sample photos to try the tool empty-handed.

2

Pick a layout and aspect

The layout row shows the grids available for your photo count, and the aspect chips set the final shape — square, 4:5, 3:2, 16:9 or a 9:16 story.

3

Tune the style

Drag photos between cells to swap them, then set the gap, corner rounding, outer margin and background colour with the sliders and swatches.

4

Download it

Press Download collage for a full-size JPG, or the PNG link under it. For one blended scene instead of a grid, press AI-blend photos in Overchat.

Who this collage maker is for

📱

Posting a photo dump as one tile

Ten carousel slots make people swipe; one clean grid makes them stop. Set 4:5 or 1:1, drop the best nine shots in, post the whole story as a single image.

🎁

Making a gift or a card

A year of photos in a 3×3, a warm background colour, a full-size download — printed and framed, that is a birthday present that took ten minutes.

🏷️

Sellers writing listings

One combined shot of every angle is the thumbnail that gets the tap on a marketplace. Up to nine product photos, one tidy grid, no watermark over your goods.

💍

After the trip or the wedding

Forty singles say nothing; one collage says how it went. Pick the shots that carry the day and let the grid do the storytelling.

📋

Mood boards and briefs

References for a designer, a stylist, a tattoo artist or a contractor land better as one file than as nine attachments. Grid them, download, send.

🔒

Anyone who won't upload family photos

The whole collage is stitched on your device — your photos never reach a server unless you deliberately press the AI blend button.

Great experience! It helps me able to do my work and respond to questions quickly trusting that the my responses are grammatically correct.

I've started to use overchat last week and it feels very promising. Lots of AI models in one place saves a lot of money in comparison if you buy subscriptions for each one.

I like how it keeps everything organized. One subscription is enough for all major AI models, which helps me avoid paying for multiple platforms.

Frequently Asked Questions

Is this collage maker really free, with no watermark?

Yes. The collage is stitched in your own browser, so there is no server bill to recover — no watermark, no sign-up, no resolution cap on the download.

How many photos can I put in one collage?

Up to nine. Each photo count from one to nine has its own set of layouts, from side-by-side pairs to mosaics to the classic 3×3 grid.

Do my photos get uploaded anywhere?

Not for the collage — reading, arranging and exporting all happen on your device. The one exception is the optional AI blend button, which sends up to four photos to the image model, and only when you press it.

What size is the downloaded collage?

2048 pixels on the long side, as JPG or PNG. That prints cleanly at about 17 cm on the long side at 300 DPI, and is more than Instagram or marketplace listings need.

Which collage size works for Instagram?

4:5 for a feed post, 1:1 for a grid tile, 9:16 for a story. All three are on the aspect chips, and the layout redraws to fill whichever you pick.

Can I rearrange photos after picking a layout?

Yes — drag any photo onto another and they trade places, right on the preview. Shuffle deals a random arrangement if you would rather not decide.

Can I add text or stickers to the collage?

Not here — this tool does grids, gaps, corners and backgrounds, and it does them without a sign-up wall. For captions or stickers, download the collage and add them in any editor, or use the AI blend to merge your photos into one scene you can keep editing in Overchat.

Does it work on a phone?

Yes. Photos come straight from your camera roll (HEIC included), swapping works with your finger, and the download saves like any other image.
