How to use the Collage Maker
- Choose 2 to 16 photos.
- Pick a layout — grid, side by side or stacked — and a shape like square or 9:16 story.
- Adjust spacing, corners and the background color.
- Download the collage.
Collages for posts, stories and comparisons
Put before-and-after shots side by side, build a square photo grid for Instagram, or stack screenshots into one image for a bug report. The grid picks the number of columns automatically, and every photo is cropped from its center to fill its cell evenly.
Going the other way — one image cut into many? Use the Image Splitter. Add a caption afterwards with Add Text to Image.
Images are edited with your browser’s canvas, so photos never leave your device — no upload, no watermark, no sign-up.

Frequently asked questions
How do I concatenate images?
Choose the images, pick Side by side (horizontal) or Stacked (vertical) and set Shape to Keep full images. They are scaled to the same height or width and joined edge to edge without cropping.
Can I join images without cropping them?
Yes. With Keep full images, nothing is cut: side by side matches the heights, stacked matches the widths, and Spacing adds an optional gap.
How do I put two pictures side by side?
Choose both photos, pick Side by side and a shape, then download.
How many photos can a collage have?
From 2 up to 16. The grid adjusts its columns to the number of photos.
Are my images uploaded?
No. Everything happens in your browser; your images never leave your device.
Can I install Collage Maker as a web app and use it offline?
Yes. Collage Maker is an installable web app (PWA) — installed from your browser, not downloaded from an app store. Click Install app at the top of this page in Chrome or Edge (Windows, macOS, Linux, ChromeOS) or on Android, use Share → Add to Home Screen on iPhone and iPad, or File → Add to Dock in Safari 17+ on a Mac. It then opens in its own window with its own icon, and because it runs entirely in your browser it keeps working offline. Firefox on desktop can’t install web apps. How installing works.
