About Compress Image to 20KB
20KB is a common limit for scanned signatures and small photos on government exam and recruitment forms. This tool compresses JPG, PNG and WebP images to 20KB or smaller by lowering quality and, only when needed, resolution — then shows the new size so you can check it before uploading. Everything runs on your device, so your photos stay private.
