Photo Stitcher — vertical, horizontal or grid
Stitch multiple images online: combine screenshots vertically into one long image (chats, web pages), side by side horizontally, or in a grid. Adjustable order, spacing and background, uncompressed PNG export. Private shots like chat logs are stitched locally in your browser — nothing uploaded. Works on desktop, tablet & mobile.
Image stitching merges several pictures into one in order: vertical for chat logs and segmented web screenshots, horizontal for comparisons and timelines, grid for product shots and tidy multi-image posts. Upload a batch, reorder items, pick the layout, columns (grid), spacing and background. Mismatched sizes are scaled to match by default (downscale only — never upscaled into blur), or keep original sizes centered. Export defaults to uncompressed PNG, because text in long screenshots hates JPG compression. Sensitive content like chats and statements is processed entirely in your browser; nothing is uploaded.
When you need it
Long chat screenshots
Stack multiple chat captures into one long image instead of sending nine files.
Comparisons / timelines
Before-and-after or step-by-step shots side by side at a glance.
Product / asset grids
Arrange product photos into clean 2-4 column grids, ready to post.
About stitching
- Vertical / horizontal / grid layouts with order, spacing and background control
- Scale-to-match by default (downscale only), uncompressed PNG export
- Private screenshots stitched locally — no upload
- Many large images use significant memory; results over 16384px per side are auto-scaled down
- Mobile browsers have tighter memory — batch large 4K sets
- PNG / JPG / WebP only
Photo Stitcher FAQ
No. Stitching runs entirely in your browser Canvas; screenshots never reach a server — exactly how private chats and statements should be handled.
By default they are scaled to match: same width for vertical, same height for horizontal (downscale only, never blurry upscaling). Or switch to "Keep original" — narrower images are centered with the background filling gaps.
Long screenshots are full of text, and JPG compression smears text with artifacts; PNG is lossless and keeps it crisp. Use the Compress Image tool afterwards if you need a smaller file.
No hard count limit — the constraints are browser memory and canvas limits: results beyond 16384px per side are proportionally scaled down with a notice; batch huge 4K sets on mobile.
