Please wait while the page loadsSign PDF lets you create and place legally binding electronic signatures on contracts, agreements, and tax forms for free. Draw, type, or upload your signature, position it on any page, and download the signed document instantly.
Sign PDF enables electronic signing of PDF documents directly in your web browser. Under the United States Electronic Signatures in Global and National Commerce Act (ESIGN Act), the Uniform Electronic Transactions Act (UETA), and the European Union eIDAS Regulation (Regulation EU 910/2014), electronic signatures carry the same legal validity and enforceability as traditional wet-ink pen signatures on paper. This tool provides three flexible creation modes: drawing your signature on a responsive HTML5 touch canvas with variable pressure strokes, typing your name or initials across elegant calligraphic and script typography styles, or uploading a photo or scanned transparent PNG of your handwritten signature. Once created, you place the signature stamp interactively onto any page, drag to reposition, resize with bounding box handles, and append automated date stamps. Processing runs locally with zero third-party tracking, ensuring sensitive contracts, lease agreements, non-disclosure agreements (NDAs), and employment offer letters remain 100% private.
