Build your layout from real thumbnails
- Add up to nine photos. Select a thumbnail to adjust that photo.
- Drag thumbnails to reorder, or use Earlier and Later. Choose a layout, spacing and background.
- Frame each photo with crop position and zoom, or keep the whole image. Prepare and inspect the actual export.
Tile layouts preserve image proportions. Fill tile crops edges; Keep whole photo adds background. The last grid row expands evenly so there are no empty grid cells. Small photos can look soft when enlarged; check the full export before sharing.
Undo and local processing
Undo and Redo keep up to 20 layout, ordering, framing and removal states. Adding photos starts a new history after the entire batch succeeds. An invalid or cancelled batch leaves your existing collage intact. The sample replaces the current collage after loading successfully. Clear releases the collage from memory and cannot be undone.
PNG/JPG processing stays on this device without uploads or automatic storage. Each input is limited to 10 MiB and 12 million pixels; the complete collage is limited to nine photos, 16 million source pixels and 30 MiB of input files. Browser orientation is applied; animated PNG becomes a still frame. Decoding and encoding have a 30-second deadline. Cancelled native work may finish, but its results cannot replace current work.
Exports contain at most four million pixels, are opaque, and remove source metadata. Transparency uses your background color. JPG is lossy; PNG can be larger. Preview decorations and ordering controls are never included in the download.
