Frequently asked questions

How do I get my signature as an image?

Sign on white paper, photograph or scan it, and crop tightly. A PNG with a transparent or plain white background blends best with the page.

Can I sign only some pages?

Yes — enter page numbers or ranges like 1-3, 5 in the pages field. Leave it empty to stamp the signature on every page.

Is this a legally binding electronic signature?

It places your signature image on the document, which many jurisdictions accept for everyday agreements. For regulated e-signature workflows with audit trails, use a dedicated signing service.
