Electronic Signature vs. Digital Signature
While often used interchangeably, there is a difference. An electronic signature (e-signature) is a digital representation of your handwritten signature—like drawing on a screen or typing your name. It is legally valid for most everyday business and personal documents. A digital signature is a highly secure, encrypted method that relies on a certificate authority (CA) to verify identity, typically required only for heavily regulated government or legal filings. Toolszu provides fast, compliant, and easy-to-use electronic signatures for all your standard PDF needs.
