Let’s get started.

What is a Digital Signature?

A digital signature is an electronic version of your handwritten signature that can be applied to digital documents such as PDFs or images. Instead of physically signing paper, users create or draw signatures online and place them directly on documents.

Digital signatures help verify identity and confirm agreement without requiring physical paperwork.

Unlike traditional signatures, digital signing allows users to:

• Sign documents instantly
• Work remotely
• Share signed files immediately
• Maintain professional workflows

Today, digital signatures are widely used in businesses, freelancing platforms, education systems, and legal processes.
