Clean a scan while preserving its character
Signature cleaning is a contrast operation, not a redraw. Adjust the paper-removal control until grey texture disappears but the natural variation in the pen line remains. If the source is blurred, heavily shadowed or photographed at an angle, making the threshold stronger can remove authentic strokes along with the paper.
Use the preview at both normal size and close zoom. Pay attention to crossings, small dots and the final pen lift. Export transparent PNG for document placement, or move to a portal-specific resizer when the receiving form lists JPEG, dimensions or a KB range.
- Retake severe shadows.
- Preserve a clean original scan.
- Compare every fine stroke before download.

Frequently asked questions
How do I turn a photo of my signature into a signature image?
Sign on plain white paper, take a clear photo or scan, and upload it here. The tool removes the paper background, trims tightly to the ink, and converts the photo into a clean signature image you can drop onto any form — exported as a white-background JPG or a transparent PNG.
What does the signature cleaner do?
It removes the paper background, auto-trims the empty space around the ink, and optimises the file size — turning a phone photo of your signature into a clean, form-ready image.
Will it keep a transparent background?
Yes. The cleaned signature is exported as a transparent PNG so it sits cleanly on forms and documents.
Can it fix a faint or shadowed scan?
Yes. Adjust the cleanup strength to lift faint paper and shadows while keeping the ink legible.
Is it free and private?
Yes — free, no watermark, and your signature is processed on your device only.
