Frequently asked questions

Is signing a PDF online safe here?

Yes — your document and signature are processed on your own device and never uploaded to a server.

Can I sign on my phone?

Yes, the signature pad works with your finger on touch screens.

Is this a legally binding signature?

It places a drawn signature image on the document, which many everyday agreements accept. For certified digital signatures with identity verification, a dedicated e-signing service is required.
