Are Electronic Signatures Legal?

Yes. In the United States (ESIGN Act), European Union (eIDAS Regulation), and most other jurisdictions, electronic signatures carry the same legal weight as handwritten ones for the vast majority of documents - contracts, agreements, consent forms, tax filings, and more.

Common Documents to Sign

• Rental and lease agreements
• Employment contracts and offer letters
• NDAs and vendor agreements
• School permission slips and medical forms
• Tax documents and financial authorizations

After Signing

• Password-protect the signed document to prevent tampering
• Compress the PDF if you need to email it as an attachment
• Add a watermark like "Signed" or "Final" for visual confirmation

Your signature and document are processed entirely in your browser. Nothing is uploaded to a server, so your signed documents remain completely private.
