Draw vs. Digital Signature: What's the Difference?

While people often use the terms "electronic signature" and "digital signature" interchangeably, they represent different levels of technology and security.

Comparison Overview

Drawn (Electronic) Signature: This is a visual mark (drawn with a mouse, typed in cursive, or uploaded as an image) placed on a PDF. It indicates agreement and is legally valid for most general business contracts, invoices, and consent forms.
Digital Signature: This uses mathematical algorithms and cryptographic keys to bind a digital certificate (issued by a Certificate Authority) to the document. It guarantees that the document has not been altered since signing and verifies the exact identity of the signer.

Which one do you need?

For 90% of daily transactions—such as signing a rental agreement, confirming a proposal, or signing an NDA—a drawn electronic signature is perfect. PrivaPDF offers a secure, zero-upload tool to draw and place signatures on your files in seconds.

Common questions

What is an electronic signature?

An electronic signature (like a drawn signature) is a visual representation of your sign-off applied to a document.

What is a digital signature?

A digital signature is a specific, cryptographically secured type of signature that uses public key infrastructure (PKI) to verify document integrity and signer identity.
