What Is PDF Signing?

Signing a PDF means placing your signature on a digital document — similar to signing a paper contract, but with much less hassle and a lot more convenience.

Why It’s Important in Today’s Digital World

With remote work, online contracts, and paperless offices becoming the norm, PDF signatures are essential for approval, verification, and legally binding agreements — all without needing to meet in person or scan documents.

✍️ Types of PDF Signatures

Electronic Signatures

These are simple image-based or text-based signatures added to a document. They're convenient and fast but lack advanced verification.

Digital Signatures

These use encryption and certificate authorities to ensure authenticity and integrity. They're more secure and legally robust.

The Legal Difference

An electronic signature is a broad category — even typing your name counts. A digital signature, however, is cryptographic and traceable.

Which One Should You Use?

If legal validity or security is critical, go digital. For informal needs or internal use, electronic signatures are just fine.
