How to Insert Signature in PDF: for PC, Mac & Mobile

Part 1: What Is a PDF Signature and Why Is It Important

A PDF signature is an electronic representation of your handwritten signature or a digital certificate that authenticates your identity. There are two primary types of PDF signatures:

• Electronic Signature: This is a scanned image of your handwritten signature or a typed version. It's commonly used for informal documents and doesn't provide robust security.
• Digital Signature: This involves encrypting your signature with a private key, providing a higher level of security and authenticity. It's often used for legal and official documents.

Using signatures in PDFs is crucial for several reasons:

• Legality: In many jurisdictions, digital signatures are legally binding and recognized in court.
• Security: Digital signatures ensure the integrity of the document and verify the signer's identity.
• Efficiency: Eliminates the need for printing, signing, and scanning documents, saving time and resources.
