Digital Signature vs Electronic Signature: What Is the Difference?

Understand the practical difference between simple electronic signatures and certificate-based digital signatures.

6 min read - Updated 2026-06-26

People often use digital signature and electronic signature as if they mean the same thing. In practice, they can refer to different levels of identity, security, and verification.

When this workflow matters

This workflow matters when a document must be clear, complete, easy to review, and ready for upload or sharing. It is especially important for tenders, compliance packs, contracts, reports, finance documents, and business records where small mistakes can delay approval.

A practical way to prepare the file

Use a simple electronic signature when you need to place a visible signature on a document. Use a certificate-based digital signature when the workflow requires stronger identity verification, tamper evidence, or formal signing controls.

Quality checks before you send it

Always check the signing requirement in the contract, tender, client instruction, or law that applies to the document. If a formal digital signature is required, a simple image signature may not be enough.

Quick checklist

  • Read the signing requirement
  • Use the right signing method
  • Keep audit records where required
  • Confirm recipient acceptance
