Digital Signature vs Electronic Signature: What’s the Real Difference?

You’ve seen the terms digital signature and electronic signature used everywhere, from HR contracts to legal memos.

Most people assume they’re interchangeable, but they’re not.

Confusing the two could mean using the wrong type of signature for the wrong kind of document. That’s where things get messy: invalid agreements, compliance issues, and delays you didn’t budget for.

Although digital signatures and electronic signatures may sound similar, they work very differently behind the scenes.

In this post, we’ll break down their key differences, when each is required, and how to stay compliant while simplifying the signing process.

Let’s start.

What is an electronic signature?

An electronic signature is any digital symbol, process, or action that indicates a person’s intent to sign a document.

It is a virtual “yes” that is simple, fast, and legally recognized.

Electronic signatures are defined and protected under laws such as:

• The ESIGN Act in the United States
• The eIDAS Regulation in the European Union

However, an electronic signature is valid as long as:

• The signer gives clear consent
• There’s intent to sign
• The method used can identify the signer and show that the document wasn’t altered after signing

Common examples of electronic signatures:

• Typing your name into a signature box
• Clicking an “I accept” button on a contract
• Drawing your signature using a finger or stylus
• Uploading a scanned image of your handwritten signature

In fact, the global electronic signature market is expected to reach $14.1 billion by 2026, driven by the shift to remote work and digital transformation across industries.

When do people use electronic signatures?

Some typical use cases of electronic signatures are:

• Offer letters and HR documents
• Vendor and sales agreements
• NDAs and consent forms
• Internal approvals and compliance checklists
• Real estate and rental documents

What is a digital signature?

A digital signature is a specific type of electronic signature that uses encryption to verify the signer’s identity and protect the document from tampering.

It’s built on Public Key Infrastructure (PKI), which uses a matched pair of digital keys:

• One private key (used to sign)
• One public key (used to verify)

This cryptographic process ensures:

• The signer is identified
• The document hasn’t been altered after signing

In short: Digital signatures capture intent and provide proof of identity and document integrity.

How does a digital signature work?

Step-by-step process:

1. You sign a document with your private key (a secure code only you have)
2. That creates a unique fingerprint tied to both your identity and the document’s contents
3. Anyone receiving the file can use your public key to verify the signature

If even a single character is changed after signing, the verification fails.

Common use cases for digital signatures:

Digital signatures are commonly used for compliance-heavy industries like:

• Filing taxes or legal documents with government portals
• Signing financial audits or shareholder agreements
• Submitting clinical research or medical records
• Securing sensitive contracts across borders

Key differences between digital and electronic signatures

Digital and electronic signatures let you sign documents online, but they operate differently.

In short:

• Use electronic signatures when you need speed, simplicity, and legal compliance
• Use digital signatures when you need identity verification, document integrity, and cryptographic proof

What is a qualified electronic signature?

A qualified electronic signature (QES) is a special category of digital signature recognized under the EU’s eIDAS regulation. It’s the most advanced and regulated form of electronic signing.

To be valid, a QES must meet three key criteria:

• It’s based on a digital signature (using encryption and certificates)
• The signer’s identity is verified in advance by a Qualified Trust Service Provider (QTSP)
• It’s created using a qualified signature creation device (QSCD), like a secure USB token or cloud-based secure environment

In simple terms,  a QES is the digital equivalent of showing your passport and signing a document in front of a notary.

According to the EU Commission, a qualified electronic signature has the same legal effect as a handwritten signature in all EU member states. 

When is a QES required?

Qualified signatures are mostly used for:

• Signing public tenders or legal filings
• Company incorporation or notarial acts
• High-stakes cross-border business agreements

Real-world examples of digital, electronic and qualified electronic signatures

Need help deciding on a signature format? These examples can point you in the right direction.

Electronic signature

Scenario: A hiring manager sends out an offer letter to a new employee. The candidate clicks a secure link, reviews the contract, and types their name to sign.

• No certificate or encryption involved
• Legally valid under ESIGN and eIDAS
• Perfect for: HR paperwork, NDAs, internal approvals, vendor onboarding

Here, the action clearly shows intent to sign. The platform captures the audit trail (IP address, time, email), and the document remains tamper-evident.

Digital signature

Scenario: A financial services firm is filing audited reports with a regulatory body. Each file must include a digital signature that proves the signer’s identity and ensures the data hasn’t been altered.

• Backed by digital certificate issued by a trusted Certificate Authority
• Encryption ensures tamper protection and authenticity
• Required for: compliance filings, shareholder disclosures, tax documents

In this case, the digital signature validates both the signer’s identity and the document’s integrity. This is critical when legal or financial consequences are the main concern.

Qualified electronic signature

Scenario: Suppose, a company is incorporated in Germany. The founding documents must be signed using a qualified electronic signature, issued by a local QTSP, and stored on a secure signature device.

• Legally equivalent to handwritten signature under EU law
• Identity verified with in-person or remote video checks
• Required for: business registration, court documents, EU public sector tenders

When the stakes are high, especially during EU legal transactions, only a QES holds the same legal power as a wet-ink signature.
