Electronic Signature vs. Digital Signature
An electronic signature is any mark applied to a document electronically to indicate agreement. Electronic signatures are legally valid for most commercial contracts under laws like the US ESIGN Act and EU eIDAS regulation. A digital signature is a cryptographically secured electronic signature that uses a certificate-based identity to verify the signer. For standard business contracts and forms, an electronic signature is sufficient.
Three Ways to Add Your Signature
Draw: Use your mouse, trackpad, or touchscreen to write your signature. This produces the most natural-looking result. Type: Enter your name and select a signature font. Typed signatures are perfectly valid for most agreements. Upload: If you have a high-quality scan of your handwritten signature as a PNG, upload it and place it on the document.

Is an Online PDF Signature Legally Binding
In most jurisdictions, yes. Electronic signatures are recognized as legally binding for the vast majority of private contracts under laws such as the US ESIGN Act, the UK Electronic Communications Act, and EU eIDAS Regulation. Certain document types are excluded including wills in many jurisdictions, specific court filings, and notarized documents.
After Signing: Protect the Document
Once you have signed a PDF, consider adding password protection before sending it. This prevents the recipient from modifying the signed document. Use the Protect PDF tool to add a password immediately after signing.
