Signature and stamp cleaner
Turn a photo of a signature or seal into a clean transparent PNG: the paper disappears and the ink stays, in its own colour, black or blue. Free, no sign-up, and it runs in your browser.

Result
Your cleaned signature appears here.
Adding it to a design saves it in your uploads, so you need to be signed in.
How to use it
- Sign on white paper and take a straight, well-lit photo (no shadow of your phone).
- Choose the photo. Move “Clean up” until the paper is gone and the lines are complete.
- Pick the ink colour, then download the PNG or add it to a design.
Questions
- Why is my signature patchy?
- The photo is probably too dark or uneven. Move “Clean up” towards “Keep faint lines”, or take the photo again in daylight with the paper flat.
- Can I use it on a bill or letterhead?
- Yes. The PNG is transparent, so it sits on any background. In Designee, press “Use in a design” to add it to a new design.
- Are my files uploaded?
- No. This tool runs entirely in your browser, so your files and text never leave your device. It works without an account.
