Reduce a photo or signature to 20 KB or less in your browser. Nothing is uploaded.
Need a photo under 100 KB for a form? Set the limit and get a JPEG that fits.
20 KB is a very small file, about the size of a modest thumbnail. Some online forms ask for photos or scanned signatures this small. To reach it, the tool lowers JPEG quality and, if needed, shrinks the picture, so expect a small, soft image.
It is enough for a small passport-style image. Expect limited detail, especially in busy backgrounds.
Crop the image tighter or resize it smaller first, then compress again.
