How to use the Photo Collage Maker
- Add photos — drag them in, paste with Ctrl+V or choose them from your phone (iPhone HEIC photos work too). They fill the layout automatically, and it grows to fit however many you add.
- Pick a layout or press Smart mosaic. Drag the lines between photos to resize them, drag a photo to reposition it, drop it on another cell to swap, and pinch or Ctrl + scroll to zoom. Select a cell to split it, delete it or add a filter.
- Style it under Design — spacing, rounded or circle cells, shadows, borders and colour, gradient, pattern or blurred-photo backgrounds — and add text, stickers or polaroid photos. Then download a JPG, PNG or WebP at up to 16 megapixels.
What does this tool do?
Most collage makers lock you into fixed grids. Here every layout is fully editable: drag any dividing line to make one photo bigger, split a cell in two or delete it, and the rest of the layout adjusts. Smart mosaic goes further — it arranges your photos in rows or columns that follow each photo’s own shape, so faces and horizons aren’t cropped off.
Canvas sizes are ready for Instagram posts, portraits and stories, Facebook, X, Pinterest, LinkedIn and YouTube, plus 4×6, 5×7 and 8×10 inch prints, A4, Letter and posters at 300 DPI. Spacing, corners and text scale with the canvas, so you can switch from a square post to a story without redesigning. Your images are processed on your own device and never uploaded. Your collage autosaves in this browser.

Frequently asked questions
Is it really free, with no watermark?
Yes. There’s no sign-up, no watermark and no limit on how many collages you make. Everything runs in your browser, so your photos are never uploaded to a server.
How many photos can I put in a collage?
Templates go up to 16 photos, and Smart mosaic arranges any number — 20, 30 or more. Add photos and the layout grows automatically to fit them.
What size should I use for Instagram?
Use Instagram post (1080×1080) for a square feed post, Instagram portrait (1080×1350) to take up more of the feed, or Story / Reel (1080×1920) for stories. Download at 2× for extra sharpness on high-resolution screens.
Can I print my collage?
Yes — choose a print size such as 4×6, 5×7 or 8×10 inches, A4 or Letter. These are set at 300 DPI, the standard for sharp photo prints. Download a JPG at 92% quality or higher, or a PNG.
Can I use photos from my iPhone?
Yes. HEIC photos are converted on your device automatically, and photos are rotated the right way using their camera orientation.
Will my collage be saved?
Your design and photos are saved in this browser on this device, so you can close the page and carry on later. Use Download to keep a copy; clearing your browser data removes the saved collage.
