About this tool

A 20 KB limit is common for signatures and small ID photos. The tool lowers the image quality step by step and, if needed, reduces the dimensions until the file is 20 KB or smaller. The work happens in your browser, so your photo is never uploaded. If the result looks too soft, try a larger limit or start with a sharper original.

Tips for best results

Use a clear photo with a plain background. It compresses better.
If the tool cannot reach 20 KB, resize the image to fewer pixels first.
Keep the original file in case you need it later.

Frequently asked questions

Is my photo uploaded?

No. Everything happens inside your browser.

Can I use this for a signature?

Yes. Crop the signature first, then compress it to 20 KB.

What if the file is a little above 20 KB?

Run it again, or use Resize Image to make it smaller before compressing.

Will my photo look blurry?

A moderate reduction is hard to notice. Very small limits may soften fine details.
