Supported image formats
Read common image formats directly in your browser. PNG is best for lossless screenshots, JPG for photos, and WebP for smaller files.
The tool uses the browser Canvas API and ImageBitmap, so your files stay local and the interface stays responsive.
Useful for
Long screenshots
Join web pages, chat captures, or tutorials into one long image.
Product galleries
Match image heights or widths for cleaner product sheets.
Social sharing
Arrange a set of photos into one easy-to-share collage.
FAQ
Frequently asked questions
Are my images uploaded?＋
No. Files are read, resized, stitched, and exported in this browser tab. They are not sent to a server.
How many images can I stitch?＋
There is no fixed count. The practical limit depends on device memory and the browser canvas size. Resize very large files first if needed.
Why match the longest edge?＋
Vertical layouts match the widest image; horizontal layouts match the tallest image so the result looks more consistent.
Which output format should I choose?＋
Use PNG for screenshots and transparency, JPG for photos, and WebP when you want a smaller modern image.
Your images stay on your device
Images are decoded, resized, stitched, and exported locally with the browser Canvas API. Nothing is uploaded.
