PHOTO COLLAGE
Photo collage / long stitch, many shots, one frame.
Upload several photos: auto-arrange in a grid, or stitch them into a tall/wide image in upload order. Tweak gap and background, then export a high-res PNG. All local.
Stitches in upload order; target edge is the width (vertical) or height (horizontal) of each image.

How do I use collage / long stitch?
Upload photos. "Grid collage" picks a near-square grid (or set columns yourself). "Long stitch" joins images in upload order at a unified edge — great for chat logs and long web pages. Both modes let you tune gap and background, preview live, then export a high-res PNG.
FAQ
Should I use grid layout or long-strip?
Grid mode computes a near-square row and column layout, or you set the columns yourself, which suits memory walls and nine-square collages. Long-strip mode joins images in upload order vertically or horizontally, which suits stitched screenshots and photo strips.
It says the result is too large, what now?
The final canvas has grown too big. Lower the target edge length, use fewer images, or reduce the cell size. Cell size and edge length multiply out to the total pixel count; note the target edge is the per-image width when stitching vertically, or its height when stitching horizontally.
Do images with different sizes get distorted?
No. Every image is cropped to the same cell size, so the layout stays tidy, but cropping trims the edges, so keep important content near the middle.
How much spacing and rounding should I use?
Spacing is the gutter between photos; 8 to 16px is usually generous enough. Rounding softens the look, 0 gives sharp corners. Formal albums suit tight spacing with square corners; social posts suit wide spacing with rounded corners.
Which formats work, and are my images uploaded?
JPG, PNG and WebP, and you can select many at once. Everything runs locally in your browser, your images never leave the device, and the export is a high-resolution PNG.
