How it works

Three steps, no sign-up

Add photos

Drag them in or choose files. Click a photo to crop it or prioritise it ×2, ×3 or ×5.

Choose a size

Print sizes such as 30×40 cm or A3, or screen sizes such as 9:16 and Full HD. The app shows the resolution you will get.

Create and save

A layout usually takes 5 to 30 seconds and gives you three variants to choose between. Ask for new ones until you find one you like, then save as PNG or JPEG.

Your photos never leave your device.

The whole layout engine runs in the browser. The server only sends the app itself. Your photos are read into the browser's memory and sent nowhere, and neither is the finished collage.

Common questions

Can a collage hold hundreds of photos?

Yes, up to 300 on desktop (up to 150 on mobile), and at least 3. For a gap-free result, 15 or more works best. With just 3 images there are very few valid layout combinations, but adding more opens up more possibilities.

Can I control how the collage looks?

Yes. Each run gives you three variants to choose between, and you can ask for new ones as many times as you like until you find a layout you like. For individual adjustments, click any image to crop it or prioritise it (×2, ×3 or ×5) so it more often gets more space.

Can I make a collage for social media?

Yes. Alongside print sizes, the size picker includes social presets at each platform's exact pixel size: square and portrait posts, 9:16 stories and reels, pins, covers and banners. Pick one and your collage is sized to post without cropping.

How long does it take to create a collage?

Most layouts take between 5 and 30 seconds. The algorithm runs across all your CPU cores in parallel, so a modern desktop is noticeably faster than an older phone.
