Compress an image to 25 KB
25 KB is a common small-upload limit for forum profiles, email signature graphics, and lightweight avatars. The tool below is set to 25 KB and finds the quality that hits it.

What fits in 25 KB
At 25 KB you have a little more room than the very tightest caps. A cropped portrait or a simple graphic holds up well, while a busy, detailed photo still softens.
If the result is too soft, resize the image smaller first so the same 25 KB covers fewer pixels and looks cleaner.
Hitting the target cleanly
The tool lowers JPG quality step by step and checks the size after each pass, stopping when it lands at or just under 25 KB. No trial and error on your end.
All of it happens locally in your browser, so your photo or signature image is never uploaded anywhere.
