About this tool
Online application forms often ask for a signature image of an exact size, for example 140 × 60 pixels and under 20 KB. This tool crops, cleans and resizes your signature to match.
“Clean background” turns the grey paper in a phone photo into pure white, so the signature looks crisp and the file stays small. Use Strong if shadows are still visible.
Frequently asked questions
Are my files uploaded to a server?
No. Everything happens inside your browser, on your own device. Your files are never sent anywhere, and the tool keeps working even if you go offline after the page has loaded.
What size should my signature be?
Use the exact numbers from the form’s instructions. Each portal sets its own pixel size and KB limit.
Why does my signature look faint?
Choose Normal instead of Strong cleaning, or take the photo in brighter light with a darker pen.
Is it free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
