Compress Image to 10KB
To get an image down to 10 KB, this tool binary-searches the JPG quality level until the file lands at or just under your target. A 10 KB ceiling is one of the strictest you will meet online, showing up in signature upload fields on exam and bank portals such as SSC and various government recruitment forms. It works, but you should treat it as a limit for small images, not full-size photos.

Who needs a 10 KB image
The 10 KB cap almost always applies to a signature or a tiny thumbnail rather than a face photo. Many Indian government and banking application forms ask you to upload a scanned signature between roughly 4 KB and 20 KB, and 10 KB is a frequent midpoint in those rules.
Because the limit is so tight, the trick is dimensions. A signature scanned at 140x60 pixels compresses to 10 KB with almost no visible loss, while the same signature at 800x400 will look blocky at that size. Crop tight and keep the pixel dimensions small before you compress.
Quality you can realistically expect
At 10 KB you will see visible quality loss on anything larger than a small graphic. Fine text edges soften and smooth color gradients can band. That is unavoidable physics, not a flaw in the tool.
The fix is to resize the pixel dimensions down first, then compress. A smaller canvas needs far less data, so the quality that remains is spent on a smaller area and looks sharper. Everything runs locally in your browser, so your signature never leaves your device.
How to use Compress Image to 10KB
- 1Drop your image into the box above (JPG, PNG or WebP in — JPG comes out).
- 2The tool automatically searches for the highest quality that fits under 10KB.
- 3If the image is dimensionally too large for the target, you'll be pointed to the resizer first.
- 4Download the compressed JPG.
Frequently asked questions
Can a photo really fit in 10 KB?
A small graphic or signature yes, a full portrait no. For a face photo, shrink the dimensions to around 150x200 pixels first; at typical passport-photo sizes 10 KB will look noticeably degraded.
Why does my signature turn blurry at 10 KB?
Usually because the image is too large in pixels. Crop tightly around the signature and reduce the width to a few hundred pixels before compressing, and the same 10 KB will look far cleaner.
Is 10 KB enough for SSC or bank form uploads?
Yes for signature fields, which commonly accept 4 to 20 KB. Always check the exact range on your form, since photo fields on the same portal usually allow a larger size.
