Electronic Signature vs Digital Signature: What's the Difference?
These two terms are used interchangeably in everyday conversation — but they mean very different things in a technical and legal context. Here's a clear breakdown.
Quick Comparison
| Feature | Electronic Signature | Digital Signature |
|---|---|---|
| Definition | Any electronic indication of intent to sign | Cryptographic signature using public-key infrastructure (PKI) |
| Technology | Image, typed name, checkbox, stylus drawing | Encryption certificates (X.509), hash algorithms |
| Verification | Based on intent and context | Mathematically verifiable, tamper-evident |
| Common use | Contracts, agreements, everyday documents | Banking, government documents, software distribution |
| Cost | Usually free or very cheap | Requires a certificate from a Certificate Authority |
| Privacy | Variable — depends on the service used | Usually tied to your identity via a CA |
What Is an Electronic Signature?
An electronic signature (or e-signature) is the broadest category. It's any electronic method of indicating intent to agree to something. This includes:
- Drawing your signature with a mouse or finger (like on Browser-Based Tools by Gleanso)
- Typing your name at the bottom of an email
- Checking a checkbox that says "I agree"
- Clicking a button labeled "Accept"
- A scanned image of your handwritten signature
Electronic signatures are legally recognized in most countries for most commercial and personal documents. They're used every day for employment contracts, rental agreements, service terms, and more.
What Is a Digital Signature?
A digital signature is a specific type of electronic signature that uses cryptographic technology — specifically Public Key Infrastructure (PKI)— to provide a mathematically verifiable proof that:
- A specific person signed the document (identity verification via a Certificate Authority)
- The document has not been altered since it was signed (tamper detection via a cryptographic hash)
Digital signatures require you to obtain a certificate from a trusted Certificate Authority (CA), similar to how HTTPS certificates work for websites. This certificate is tied to your identity.
Examples of digital signatures in use: signing software (code signing), PDF digital signatures in Adobe Acrobat, government document signing systems.
Which One Do You Actually Need?
For most everyday documents → Electronic Signature
Contracts, NDA agreements, rental agreements, employment documents, freelance invoices, consent forms, email correspondence. An electronic signature is legally sufficient in nearly all cases under laws like ESIGN (USA), eIDAS (EU), and similar frameworks.
For high-trust or regulated documents → Digital Signature
Financial instruments, government tax filings, healthcare records (in some jurisdictions), legal documents requiring notarization, software distribution. These require the cryptographic guarantees that only a PKI-based digital signature provides.
How Browser-Based Tools by Gleanso Fits In
The Signature Generator on Browser-Based Tools by Gleanso creates an electronic signature — specifically, a drawn signature image. This is appropriate for the vast majority of everyday document signing scenarios.
Because everything runs in your browser with no uploads, it's also one of the most private ways to create an e-signature — you're not handing your signature to a cloud service.
