About Compress Image to 30KB
30KB is a common limit for photo and signature fields on online application forms that cap uploads at 30KB. This tool compresses JPG, PNG and WebP images to 30KB 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.
