Compress Image to 10KB
10KB is one of the strictest limits you will meet online — it appears on avatar fields, signature boxes, and legacy form systems that cap uploads hard. This tool automatically balances JPEG quality and dimensions to land your image just under 10KB while keeping it as sharp as possible.
100% private — this tool runs in your browser. Your image is never uploaded to any server.

Frequently asked questions
Why does my photo need to be under 10 KB?
Online application portals set hard upload limits to keep their servers fast. If your file is even 1 KB over the 10 KB limit, the form rejects it. This tool compresses to just under the limit so the upload passes on the first try.
Will compressing to 10 KB make my photo blurry?
The tool finds the highest possible JPEG quality that still fits under 10 KB, and only reduces dimensions if quality alone is not enough. For typical photos the result stays clearly recognizable, which is what verification officers check for.
Is my photo uploaded to a server?
No. Compression runs entirely inside your browser using the HTML5 canvas. Your photo never leaves your device, which also makes the tool work on slow connections.
