What Is a Digital Signature?

A digital signature is a secure, verifiable way to sign documents online — no printing, scanning, or mailing required. Think of it as your handwritten signature, just smarter.

Backed by encryption, it verifies both the signer’s identity and the integrity of the document. Whether you’re sending a contract, invoice, or NDA, a digital signature ensures it’s authentic and tamper-proof.

Smoother Business Processes

Manual paperwork slows things down. Waiting for signatures, managing physical docs, and tracking who signed what is a full-time job on its own.

With a digital signature solution, these steps become automatic. You can create a digital signature, drop it into your PDF, and have a signed contract back in minutes — not days.

From onboarding employees to closing deals, using digital signature software streamlines your workflows and gives your team time back to focus on actual work.
