How to use

1. 1
   Add your images

   Drag images onto the drop zone or click Browse image files to pick them from your device. JPEG, PNG, and WebP files up to 50 MB each are supported. For best results, we recommend using 20 or more images — the more you add, the more flexibility the collage has to fill every gap.

   Tap any image to adjust it: give it more space in the collage (×2, ×3, or ×5 emphasis) or crop it to a specific region.

2. 2
   Choose your format

   Select Print or Screen. For print, pick a standard paper or poster size — the output resolution is set automatically to match 300 DPI. For screen, choose a display preset (HD, Full HD, 4K) or a ready-to-post social size at the exact pixels each platform expects: square and portrait posts, 9:16 stories and reels, short-video formats, pins, and profile covers and banners for all major platforms. You can also enter a custom size and lock its aspect ratio. Set a custom border width and colour here if you want one.

3. 3
   Create

   Click Create collage. The layout is generated entirely on your device — nothing is uploaded. A progress bar shows how the layout is coming together. When it finishes, the full-resolution collage renders automatically.

   If you're not happy with the result, click Regenerate collage for a fresh attempt, or go back and adjust your images or format.

4. 4
   Export

   Click Export → to head to the export step. Choose PNG (lossless) or JPEG (smaller, with adjustable quality) and download the full-resolution collage to your device. The save is instant — your images never leave your browser.
