Are Digital Signatures Legally Binding?

In most cases, yes. Electronic signatures are legally recognized in the majority of countries:

• United States — The ESIGN Act (2000) gives electronic signatures the same legal standing as handwritten ones
• European Union — The eIDAS regulation recognizes electronic signatures for cross-border transactions
• Canada, Australia, UK — All have legislation accepting electronic signatures for most purposes

Exceptions: Some documents still require a wet-ink signature or a qualified digital signature with a certificate — these typically include court filings, certain government forms, notarized documents, and wills. When in doubt, check with the requesting party.

Tips for Better PDF Signatures

• Use a touchscreen — Drawing your signature on a tablet or phone with your finger or stylus gives the most natural result
• Transparent backgrounds — If uploading a signature image, use a PNG with a transparent background so it blends seamlessly with the document
• Protect after signing — Lock down your signed document with a password using the Protect PDF tool so it can't be tampered with
• Need to fill in fields too? — Use the Edit PDF tool to fill in form fields, add text, or make annotations before or after signing
