Digital Signature vs Electronic Signature: What Is the Difference?

July 14, 2026 · By SEDI Editorial Team · 6 min read · Updated August 3, 2026

The terms digital signature and electronic signature are often used interchangeably, but they refer to different technologies with different security properties. Understanding the difference helps you choose the right method for your document.

What is an electronic signature?

Electronic signatures are defined broadly under laws like the US ESIGN Act. The key legal requirement is intent to sign. The Signature tool creates electronic signatures by embedding signature images into PDF files at the positions you specify.

Electronic signatures are suitable for most business documents including contracts, offer letters, purchase orders, and non-disclosure agreements. The legal validity comes from the signing process and the evidence of intent.

What is a digital signature?

Digital signatures require a digital certificate issued by a trusted Certificate Authority (CA). The certificate validates the signer identity. The signing process creates a unique hash of the document, which is encrypted with the signer private key. Any modification to the document after signing breaks the signature and can be detected.

Major e-signature platforms offer digital signature options. These are usually paid services that manage the certificate lifecycle and provide audit trails, though trial or limited free access changes over time, so check current terms.

Which one should I use?

Consider the risk profile of the document. A signed invoice or service agreement between established business partners does not need cryptographic verification. A multi-million dollar acquisition agreement likely benefits from the additional security of a digital signature.

If you are signing documents for personal use or small business, an electronic signature created with a browser-based tool is practical and legally valid.

A quick comparison

An electronic signature captures intent to sign. It is easy to create with a drawn signature, a typed name, or a checkbox, and it works for most everyday business documents. No certificate or setup is required, but the assurance is procedural rather than cryptographic.

A digital signature proves identity and detects tampering. It requires a certificate from a trusted authority and a cryptographic key exchange. It is stronger against disputes, but it takes more effort and usually involves a paid service. Any change to the document after signing breaks the signature and is easy to detect.

The legal side of electronic signatures

Electronic signatures are recognized by law in most countries. In the United States, the ESIGN Act gives them the same legal status as handwritten signatures. In the European Union, eIDAS does the same and adds tiers, with qualified digital signatures carrying the highest legal weight.

What matters for validity is intent. A signature is valid when the signer deliberately attaches it to the document. Keeping a copy of the signed file and a record of when it was signed helps if validity is questioned later.

When a drawn signature is not enough

Some documents are expected to use digital signatures: regulated financial filings, some government submissions, and contracts where one side needs to prove the other party's identity beyond doubt. In those cases, a drawn image alone may not meet the requirement.

If you are unsure whether your document needs a digital signature, ask the recipient or a legal professional before signing. The cost of a digital signature is small compared to redoing a rejected filing.

Where Signature fits

Signature creates electronic signatures. It embeds your drawn or uploaded signature into the PDF with your consent and intent, in your own browser. It does not issue digital certificates or provide identity verification. For everyday contracts, agreements, and forms, that is enough; for regulated or high-value documents, use it together with a certified digital signing service.

Frequently asked questions

Is an electronic signature as valid as a handwritten one? In most jurisdictions, yes, when the signature shows intent and both parties agree to use electronic signatures.

Can I turn an electronic signature into a digital signature? Not directly. Digital signatures require a certificate and a key pair issued by a trusted authority. The signed file would need to be signed again with that infrastructure.

Common misconceptions

People often assume a digital signature is simply an image of a signature saved in a special format. It is not. The word digital refers to the cryptography behind it, not to the fact that the signature is on a computer. A drawn signature, a typed name, and a certificate-based digital signature are all electronic; only the last one is cryptographic.

Another misconception is that every paid e-signature tool produces a digital signature. Most commercial tools create simple electronic signatures by default and offer digital signing as an option for documents that need it. Treat any claim that a checkbox or typed name is a digital signature with caution; real digital signatures rely on a certificate issued by a trusted authority.

How to know which one you need

Ask two questions. First, does anyone need to prove who signed, after the fact, with high confidence? If the answer is yes, a digital signature helps. Second, does the recipient or the regulation require it? Government filings, regulated financial documents, and some international contracts state the requirement up front.

For documents between people who know each other, where the email trail and the signed file are enough evidence, a simple electronic signature is the practical choice. It is faster, free, and fully valid for the overwhelming majority of everyday agreements.

Can a document have both?

Yes. Many workflows combine both: an electronic signature for the visible, personal sign-off, plus a digital seal or certificate underneath that protects against tampering. The visible signature gives the document a human touch, while the cryptographic layer provides the technical proof. Professional platforms bundle these into one signing ceremony.

For most documents, the visible signature alone is sufficient. The combination becomes valuable when the document's value is high enough to justify the extra setup.

Which one do you need?

Use an electronic signature for speed and convenience on everyday documents, and reach for a digital signature when identity proof and tamper detection matter more than speed. Knowing the difference keeps you from overpaying for security you do not need, or underprotecting a document that deserves it.
