Signature resize and clean up
Signature turns a phone photo of a signature on paper into crisp ink on a white or transparent background, cropped tight, and can then resize it to a form's KB and pixel rule.
How to use it
- Sign on plain white paper and take a photo in good light.
- Add the photo; the tool removes the paper and shadows and crops to the ink.
- Choose white or transparent background and ink colour.
- Download, or send it to Fit to size for a form's KB limit.
Questions
How do I make my signature a transparent PNG?
Add a photo of your signature and choose Transparent. The paper is removed and only the ink is kept, so you can place it on documents.
How do I resize a signature to 10–20 KB?
Clean it here, then press Fit to size and enter the form's KB range and pixels, or pick its preset.
Are my photos uploaded anywhere?
No. Everything happens inside your browser on your own phone or computer. Your photos are never sent to a server, so nobody else can see them, and the tool keeps working without internet once the page has loaded.
Is it free? Is there a watermark?
It is free, needs no sign-up, has no daily limit and never adds a watermark to your images.
