The best method for signing your PDF depends on the level of security and formality required. Here's a breakdown of common approaches:
1. Using a Digital Signature (Most Secure):
A digital signature offers the highest level of security and verification. It uses a digital certificate to cryptographically link your identity to the signature.

- Advantages: Simple, readily available, no extra software needed.
- Disadvantages: Least secure option, easily forged, not suitable for legally binding documents.
