Signature cleaner turns a phone photo of your signature into a clean image with a transparent or white background, ready for PDFs, forms and documents. It evens out shadows, removes the paper colour and trims the edges.
When to use Signature cleaner
- Add your signature to a PDF with Sign PDF or Edit PDF
- Upload a signature to an exam or job form that asks for a JPG
How to use Signature cleaner
- Sign on plain white paper with a dark pen and take a photo.

- Choose the ink colour and line thickness, then download a transparent PNG and a white-background JPG.
Tips
- Take the photo in daylight, straight from above, without your phone's shadow on the paper.
