Digital Signature vs. Electronic Signature: What's the Difference?
These two terms get used as if they mean the same thing. They don't - and the difference matters if a document's legal validity is on the line.
"Just sign it electronically" gets used to mean two genuinely different things, and the difference isn't just semantic - it affects what a signature can prove about who signed and when.
Electronic signature: the broad category
An electronic signature is any electronic mark made with the intent to sign a document - a typed name, a drawn signature, a scanned image of a handwritten signature, even clicking an "I agree" button in some contexts. What makes it valid isn't the visual form, it's clear evidence of intent. This is what most everyday contracts, forms, and agreements use.
Digital signature: a specific, cryptographic method
A digital signature is a narrower, technical term - it uses a cryptographic certificate tied to the signer's identity to create a tamper-evident seal on the document. If the document is altered after signing, the digital signature becomes invalid, which is what makes it useful for high-stakes documents where proving both identity and document integrity matters.
So which one do you actually need?
- Everyday agreements, internal approvals, most contracts between individuals or small businesses - a basic electronic signature (typed, drawn, or pasted-in) is standard and legally recognized in most jurisdictions
- Regulated industries, government filings, or anything requiring strict proof of signer identity and document integrity - that's when certificate-based digital signatures come in
- When in doubt for something legally significant, check what the receiving party or jurisdiction specifically requires rather than assuming
The bottom line
For the vast majority of documents people sign day to day, a typed or drawn electronic signature is perfectly valid - that's exactly what filling out and signing a PDF covers. Reach for a certificate-based digital signature only when the document specifically calls for that stronger level of proof.
Frequently asked questions
Is a typed name at the bottom of a PDF a real signature?
In most jurisdictions, a typed name with clear intent to sign counts as a valid electronic signature - it's the intent and context that matter legally, not the visual style of the mark.
Do I need a digital signature (with a certificate) for a normal business document?
Usually not - a basic electronic signature is sufficient for the vast majority of everyday agreements. Certificate-based digital signatures are typically reserved for higher-stakes documents where verifying the exact signer's identity cryptographically matters.
Can I add an electronic signature to a PDF myself?
Yes - typing your name, drawing a signature, or placing an image of your signature into the document with [a PDF editor](/edit) all count as valid electronic signature methods for most everyday purposes.
