Add Signature to PDF Free Online

Sign PDF documents free online. Draw, type, or upload your signature. No printing, no scanning needed. Legally recognized e-signatures. No signup required.

Adding a signature to a PDF no longer requires printing the document, signing by hand, and scanning it back. Our free Sign PDF tool lets you add electronic signatures directly to PDF documents from any device — computer, tablet, or smartphone. We offer three signature methods to suit your preference. Draw your signature using your mouse, trackpad, or touchscreen for the most personal result. Type your name and choose from multiple signature-style fonts for a clean, professional look. Or upload an image of your handwritten signature for the most authentic appearance. Electronic signatures created with our tool are legally recognized in most countries under e-signature laws including the US ESIGN Act, EU eIDAS Regulation, and similar legislation worldwide. For standard business documents, contracts, and agreements, e-signatures carry the same legal weight as handwritten signatures. The signature placement is fully customizable. Click anywhere on the PDF page to position your signature, then resize and adjust it to fit the signature field. You can add multiple signatures to different pages of the same document, which is useful for contracts that require initials on every page. After signing, the signature becomes a permanent part of the PDF. For additional security, flatten the document to prevent the signature from being moved or removed, and add password protection to prevent unauthorized access to the signed document.
