A photo under 20 KB that still looks clear
20 KB is one of the strictest limits on online forms, often for signatures and small photos. The tool finds the best JPG quality that fits and, only if that isn’t enough, makes the image smaller in pixels — and tells you the new size.
Always under 20 KB
The download is guaranteed to be below 20,000 bytes.
Best quality that fits
It uses as much of the 20 KB as possible, so the photo stays as sharp as it can.
JPG, the format forms accept
PNG and WebP images are saved as JPG; see-through backgrounds turn white.
Private
Your photo and signature are processed on your device, never uploaded.
How to use
