Frequently Asked Questions
Is this a legally binding electronic signature?
It adds a visual image of your signature to the document, which is accepted for many everyday agreements. It is not a certificate-based digital signature, so documents that legally require a qualified or certified e-signature need a dedicated signing service.
Is my PDF uploaded to a server?
No. The PDF and your signature are processed entirely in your browser and never leave your device.
Can I sign on my phone?
Yes. The drawing pad works with touch, so you can sign with your finger and place the signature with a tap.
How do I get a clean signature from a photo?
Sign on plain white paper with a dark pen and take a well-lit photo. Near-white background pixels are made transparent automatically, so only the ink is placed on the PDF.
