Digital vs. Electronic Signatures—What’s the Difference?

• Digital signatures use encryption + certificates = better security and compliance. Use for financial, legal, or government-related docs.
• Electronic signatures are faster and simpler. Use for internal docs, NDAs, and quick approvals.

Use digital signatures when you're dealing with sensitive legal documents, financial transactions, or regulatory compliance.

Use electronic signatures for quick approvals, NDAs, contracts, or anything that doesn't require strict identity verification.

Signwith.co offers secure, legally compliant electronic signatures perfect for common signing needs.

Choose based on your needs.
