What are digital signatures?

Digital signatures are a computerized alternative to the conventions of signing documents with pen and paper. The digital signature process typically happens entirely online, and requires the signers to add their signature to documents in a secure manner such that it can be tracked back to them and tracked in real time. This technology has now started to replace hand-drawn signatures in business transactions where documents, such as contracts, invoices, or other forms, are signed and sent electronically using a digital signature app like Zoho Sign.

Are digitally signed PDFs legal?

Yes, documents that carry a digital signature are legally valid and can be produced in court. Digital signature apps like Zoho Sign have provisions to ensure both the authenticity of the signers and the integrity of the signed documents, and thus comply with the various electronic signature laws worldwide that grant these digitally signed PDFs the same validity as physically signed documents.
