Compress Image to 10 KB
The short answer
10 KB is very small. It holds a signature or a thumbnail, not a full photo. Add your image below with the 10 KB target already set, and the tool lowers the quality and, if needed, the pixel size until it fits. Expect a plainer, softer picture.
PNG photos are saved as JPG or WebP so they get smaller.
We lower the quality, and the picture size if needed, until it fits. 1 KB is counted as 1,000 bytes, which is safe whichever way a website counts.
Your files stay on your device. This tool runs entirely in your browser and nothing is uploaded to a server.
How to: Compress Image to 10 KB
- 1Choose your image. A signature on white paper works best, because plain white squeezes into almost nothing.
- 2Check that the target says 10, or type the number from your form.
- 3Press Compress image, then look at the picture and the size next to it.
- 4Save the file. If the tool says it could not reach 10 KB, make the picture smaller in pixels first with the Image Resizer.

Frequently asked questions
Can a normal photo be 10 KB?
Only a very small one, around 100 by 120 pixels. A limit of 10 KB is meant for signatures. For photos most forms allow 20 KB or more, so read the number on the form again.
Why does my signature look grey after compressing?
A phone photo of paper is grey and uneven. The Exam Photo & Signature Maker whitens the paper and darkens the ink first, so the signature stays sharp even at a tiny size.
