FAQ About Signing PDFs Online
Is an electronic signature legally binding?
Yes, an electronic signature created when you sign PDF online using PDNOB Sign is legally binding worldwide. Our solution complies with major regulations like SES, ESIGN Act, and UETA to ensure your free PDF signature is valid and enforceable.
What is the difference between an electronic signature and a digital
signature?
While "electronic sign" and "digital sign" are related, they are not exactly the same:
Electronic Signature (e-signature) -
This is a broad term for any electronic process that indicates acceptance or approval of a document.
It can be as simple as typing your name, clicking “I agree,” or drawing your signature with a mouse
or finger.
Digital Signature -
This is a specific type of electronic signature that uses cryptographic technology to secure and
verify the signer’s identity and the integrity of the signed document. Digital signatures are
generally more secure and legally robust because they include encryption and
certificates.
In short: All digital signatures are electronic signatures, but
not all electronic signatures are digital signatures.
PDNOB Sign supports both - digital and electronic signatures with legal compliance,
secure signing with encryption and authentication.
