FAQ

Sign PDF - questions, answered

  • Is this a legally-binding eSignature?

    It applies a visible signature image to the PDF, which is accepted by most informal and business contexts. For legally-binding digital signatures with cryptographic proof, you need a certificate-based tool like Adobe Sign or DocuSign.

  • Can I place the signature on any page?

    Yes - drag the signature box onto any page, resize it, and we'll stamp it at the chosen position.

  • Can I save my signature for next time?

    Signatures are stored locally in your browser (not on our server) so they're available next time you visit.

  • What about Bangla signatures?

    Yes - draw in any script. The drawing is rendered as an image, so any language works.
