Electronic Signature vs. Digital Signature: What’s the Difference?

When working with PDF documents, you often hear the terms "Electronic Signature" and "Digital Signature" used interchangeably. However, they are not the same thing. Understanding the difference is crucial for legal documents, invoices, and business contracts.

What is an Electronic Signature?

An electronic signature (e-signature) is simply a digital version of your handwritten signature. It is an image, symbol, or process attached to a document to indicate consent.

Common examples:

• Signing a PDF using a tool like Scan4U.
• Typing your name at the bottom of an email.
• Clicking an "I Agree" button on a website.

For most daily tasks like signing rent agreements, invoices, or application forms, an Electronic Signature is legally sufficient.

What is a Digital Signature?

A digital signature is a more advanced and secure type of e-signature. It uses cryptographic technology (like a digital certificate) to verify the identity of the signer. It acts like a "digital fingerprint" for the document.

If the document is altered after signing, the digital signature becomes invalid. This is mostly used for highly sensitive government or banking documents.
