About this tool
A 10 KB signature limit is very small, so the picture also needs few pixels. This page starts with 140 by 60 pixels and a 10 KB limit. You can change both to match your form.
How to use it
- Photograph your signature on plain white paper and choose the picture.
- Check the width and height. Change them to what your form asks for.
- Check the maximum file size in KB, or clear it for no limit.
- Press Resize Image and download your signature.
A signature under 10 KB
At 10 KB every detail counts. A dark pen on clean white paper gives the sharpest result, while a pencil or a shadowed photo gives a grey and grainy one.
Crop away empty paper before you start, so the signature fills the picture. The tool will then spend its limited bytes on the writing, not on blank space.
Common questions
Is 10 KB enough for a readable signature?
Yes, if the picture is small and the ink is dark on white paper. A signature has few details, so it compresses very well.
The result looks rough. What can I do?
Use a slightly larger limit if your form allows it, or take a clearer photo with a darker pen.
Can I change the pixels?
Yes. Change the width and height before you press the button.
Is my photo uploaded?
No. The picture is processed inside your browser and never leaves your device.
