FAQ

Is my document uploaded?

No. Your PDF and your signature stay in your browser and never leave your device. The signature is forgotten when you close the page.

Is this signature legally valid?

A signature image like this is accepted for many everyday documents, such as forms, letters and simple agreements. Some contracts need a certified digital signature instead; check with whoever asked you to sign.

How do I sign with a photo of my signature?

Sign on white paper, take a photo, then choose Upload in the signature window. The white background is removed automatically so only the ink remains.
