Esignature vs Digital Signature: What’s the Difference?
People often use the terms eSignature and digital signature interchangeably, but they’re not the same thing. Both help you sign documents electronically, but they work differently and serve different purposes.
Let’s break it down in a simple, no-jargon way.
What Is an eSignature?
An eSignature (electronic signature) is any digital way of expressing your intent to sign a document.
It can be:
- Drawing your signature on a screen
- Typing your name
- Uploading a scanned signature
- Clicking “I Agree” or “Accept”
If the platform captures who signed and when, the eSignature becomes legally valid in most countries.
Everyday use cases:
Signing PDFs, agreements, offer letters, onboarding documents, NDAs, invoices, and consent forms often use advanced electronic signatures. Think of it as a digital version of your handwritten signature, simple, fast, and user-friendly.
What Is a Digital Signature?
A digital signature is a specific type of eSignature backed by cryptographic technology. It uses encryption, certificates, and a unique digital ID issued by a certifying authority (CA).
This adds an extra layer of verification and ensures:
- The signer is authentic
- The document hasn’t been tampered with
- The signature is traceable and highly secure
Digital signatures are often required for regulated, high-security workflows.
Everyday use cases:
Income tax filings, GST filings (India), bank workflows, government forms, highly confidential contracts.
It is a high-security lock with a digital certificate proving exactly who signed.
Both of them are legal, but digital signatures offer stronger identity proof and document integrity.
Which one should you use- eSignature or Digital Signature?
Use an eSignature when you want:
✅ Quick signing
✅ Easy collaboration
✅ Legally valid signatures for most business documents
Use a digital signature when you need:
✅ High-level authentication
✅ Cryptographic proof
✅ Regulatory compliance (government, tax, banking)

Pricing Considerations
Most providers provide tiered plans. While entry-level eSignature plans in Illinois do include options to digital esign for free online, the advanced cryptographic features of a digital signature appear higher in the tiers. Digital signature pricing reflects value in stronger authentication, audit logs, and compliance certifications that pay off for enterprise and regulated use cases.
