Compress Image to 100KB
100KB is a common cap for ID photo uploads, exam portals, and lightweight web pages. Retouchr searches for the best JPEG quality that still fits under 100KB, downscaling the image automatically if the quality alone can't get there.
No account, no upload — the whole process runs in your browser using canvas APIs built into the page.

FAQ
Will it be exactly 100KB?
It lands at or just under 100KB. The tool favors quality, so it stops as soon as it finds the highest quality that still fits the cap, which is usually slightly under 100KB.
Is 100KB enough for a portrait or ID photo?
Yes, for typical ID/passport-style photo dimensions 100KB is usually plenty for a clear, sharp result — larger action photos may need more downscaling.
Can I compress multiple photos to 100KB at once?
Yes — load several images and use the "All" scope toggle in the tool to apply the same 100KB target to every image in one click.
