How it works
What is the digital signature in PDF?
A digital signature in a PDF is a secure and legally binding way to sign documents electronically. It uses cryptographic techniques to ensure the authenticity and integrity of the signed document. This signature verifies the identity of the signer and confirms that the document has not been altered after signing. In the United States, digital signatures are recognized under the Electronic Signatures in Global and National Commerce (ESIGN) Act, providing the same legal standing as traditional handwritten signatures.

Legal use of the digital signature in PDF
In the U.S., digital signatures are legally valid and enforceable in most circumstances, thanks to the ESIGN Act and the Uniform Electronic Transactions Act (UETA).
