Why forms ask for 20 KB
Having to compress image to 20KB is a typical step when filling in an exam, recruitment or government application online: the form asks for a scanned signature, and sometimes a passport-size photo, with a strict maximum weight. A picture taken with a phone weighs several megabytes, so it is refused.
20 KB is very small, so start from a good image. Crop tightly around the signature or the face before compressing: fewer pixels means more quality left for what matters. For a signature, sign in black or dark blue ink on plain white paper, with even light. If the form also sets dimensions in pixels, crop to roughly that shape first.
Frequently asked questions
How do I compress my signature to 20KB?
Photograph or scan the signature on white paper, crop it tightly, then add it here. The 20 KB target is preset: the tool lowers the quality, and the size if needed, until the file fits.
How do I reduce a photo to 20KB without it looking blurry?
Crop around the face first, as a passport photo would be, and use a plain, well-lit background. A tighter crop leaves more room for detail within 20 KB. JPG usually gives the best result for photos.
Is my photo sent anywhere?
No. The image is compressed directly in your browser: nothing is uploaded to our servers, your photo never leaves your device.
Which format should I choose?
Use the format the form asks for, most often JPG. Keep JPG for photos; a signature can be JPG or PNG depending on what is accepted.
Is it free?
Yes, free and without an account. You can compress up to 20 images at a time.
