Need a photo or signature that is 20 KB or smaller? Add it below and this tool will automatically test quality levels — and, if needed, slightly smaller dimensions — until the file fits your limit.

How to reduce an image to 20 KB

1. Add your photo or signature. Tap the box or drag the file in. Nothing leaves your device at any point.
2. Press the button. The tool re-saves your image again and again at different quality settings, looking for the best-looking version that is still 20 KB or less.
3. Start small for photos. 20 KB is a tight budget, so dimensions matter more here than at any larger size. If a photo still looks soft, first bring it down to roughly the size the form displays (a few hundred pixels wide) with the Image Resizer, then run it through this tool — the same 20 KB looks far better spread over fewer pixels.
4. Download and upload. Save the result and use it in your form. Your original file is unchanged.

Who asks for 20 KB or under?

Limits this strict are common on high-volume application systems that were built to accept thousands of uploads a day on modest servers. Many Indian government job and exam application portals, for example, have long set very small caps on applicant photos, and scanned signatures on such portals are often capped even lower — around 10–20 KB — because a signature is mostly white space and a few dark strokes. University admission and scholarship forms, older corporate and banking application systems, and some document-upload flows for certificates and ID proofs use similarly small limits. If a form is rejecting your upload and the fine print mentions 20 KB, this is the tool built for exactly that line of fine print. Our guide to compressing an image to 20KB or under walks through the resize-first method in full, including the pixel sizes that make the target reachable.

Honest note: 20 KB suits some images far better than others. Signatures, stamps, ID-style photos at small dimensions and simple graphics compress to 20 KB and stay perfectly readable. A detailed, full-size photo — a group shot, a landscape, a page of fine print — will soften heavily at this size, because there simply are not enough bytes to hold its detail. If a photo genuinely cannot reach 20 KB at a readable size, the tool tells you plainly and gives you the smallest file it could make, plus a tip: crop tightly to the important part, resize first, and try again.

Need a different limit? The same automatic search is available preset to 50 KB, 100 KB and 200 KB, and the general Compress Image tool gives you a manual quality slider for any other target.
