E-Signature vs Digital Signature — Key Differences Explained

An e-signature (electronic signature) is any electronic mark that indicates agreement or approval. This includes drawing your signature on screen, typing your name, clicking 'I agree', or inserting an image of your handwritten signature. E-signatures are legally binding in most countries under laws like the US ESIGN Act, EU eIDAS Regulation, and UK Electronic Communications Act.

A digital signature is a type of e-signature that uses Public Key Infrastructure (PKI) cryptography to verify the signer's identity and confirm the document hasn't been modified after signing. It involves a digital certificate issued by a Certificate Authority. Used in high-security contexts like banking, government filings, and regulated legal contracts.

Yes, in most jurisdictions. A drawn e-signature — created with a mouse, stylus, or finger — is legally binding for most contracts and agreements in the US, UK, EU, Australia, India, and many other countries. The key factors are intent to sign and consent to use electronic signatures, not the visual style of the signature.

For most contracts — employment agreements, rental leases, service agreements, NDAs — a simple e-signature is legally sufficient. You only need a cryptographic digital signature for specific regulated documents like certain government filings, notarised documents, or contracts in industries with specific legal requirements. When in doubt, consult a lawyer.
