Resize an image to 10 KB
Ten kilobytes is about as small as a usable image gets. It is almost never meant for a face photo — at that size a colour portrait turns into coloured blocks. It is the limit forms set for a signature, a thumb impression or a small logo, and for those it works well, because ink on paper is mostly white space and white space compresses to almost nothing.

This size is for signatures, not faces
If a form asks for 10 KB, read it again carefully. Nearly always that number belongs to the signature box, while the photo box next to it allows 20, 30 or 50 KB. People fail this step by resizing the photo to the signature limit, uploading an unreadable picture, and getting the application rejected for an unclear photograph.
Why a signature fits and a photo does not
A JPG stores detail. A signature has very little of it: a few dark strokes on a plain background, so most of the image is one flat colour and the file stays tiny even at good quality. A face has skin tone, shadow and texture in every square millimetre, and all of that has to be thrown away to reach 10 KB.
Crop to the ink first
- Photograph or scan the signature on plain white paper in even light.
- Crop so the signature almost fills the frame. Blank paper around it wastes the budget you have.
- Keep it straight. A tilted scan looks careless and some portals reject it.
- Check the strokes are still solid after resizing. Broken, faded lines mean you went too far.
If 10 KB truly is the photo limit on your form, crop to head and shoulders only and accept that the result will be soft. Then check whether the form also states a minimum size, because a very small file can fail that test instead.
Steps
- Choose the scan or photo of your signature.
- The limit is already set to 10 KB on this page.
- Check the size shown beside the image, and that the strokes are still solid.
- Press Download and upload the file to your form.
Questions
Can a face photo work at 10 KB?
Rarely. Cropped tight to head and shoulders it can just about pass, but it will look soft. Check whether 10 KB is actually your form’s signature limit rather than its photo limit.
My signature came out faded and broken. What now?
Crop closer so the signature fills more of the frame, and scan on plain white paper. Less empty background means more of the 10 KB is spent on the strokes themselves.
Is my file uploaded anywhere?
No. The resizing happens inside your browser, so signatures and ID photos stay on your device.
