Your files never leave your device: Compress image to 10 KB runs inside your browser, so nothing is uploaded, stored or seen by anyone. It is free and needs no sign-up.
Ten kilobytes is very small, about the size of a short text file. It suits the tiniest upload boxes, such as a signature, a thumbprint or a stamp-size photo on an application form. Expect a small picture with soft detail: a large photo cannot reach 10 KB without losing sharpness.
For a signature, write in dark ink on plain white paper and photograph it in daylight. Plain backgrounds shrink far better than busy ones, so crop tightly around the writing before you compress.

Questions and answers
- Can a whole photo fit in 10 KB?
- Only a small one. At 10 KB the tool lowers the size and quality until the file fits, so faces turn soft. For a passport-style photo, 20 KB or 50 KB is usually a better target.
- My signature is still too large. What now?
- Crop closer to the writing, use dark ink on plain white paper, and try again. Less empty space means fewer details to store.
- Are my files uploaded anywhere?
- No. Your browser opens and processes the files itself, and nothing is sent to our servers. You can check this yourself on the How we do it page.
- Is my original photo changed?
- No. You get a new file to download and the original stays where it is. Check the result before you replace anything.
- Is Compress image to 10 KB really free?
- Yes. There is no sign-up, no watermark and no limit on how many files you use it for.
