The free Online Signature Maker and PDF Signer lets you create a handwritten signature and place it on PDF documents, all inside your browser. Your signature is drawn on an HTML5 canvas with your mouse or finger (on mobile); it is never uploaded to any server. This addresses a major concern for remote workers and anyone signing contracts or official documents: banks and institutions often warn against uploading signatures to unknown sites. Here, the signature is generated and stored only in your device memory until you add it to a PDF and download the result.

To create your signature: use the drawing area to write or draw your signature. You can clear and redraw until you are satisfied. Optionally download the signature as a transparent PNG for reuse elsewhere. To sign a PDF: upload your PDF file, then click to add your signature to the document. The tool uses pdf-lib to embed the signature image into the PDF at the chosen position. You get a new PDF with your signature on it, ready to send. Ideal for contracts, agreements, consent forms, and any document that requires a formal or bank-style signature without exposing it to the internet.

Electronic signatures are legally recognized in many jurisdictions when they reflect the signer’s intent. This tool supports that workflow while keeping full privacy: drawing and placement happen locally, and only the final signed PDF is in your hands. No account, no cloud storage, no third-party access to your signature. Use it for employment contracts, NDAs, rental agreements, or any document you need to sign quickly and securely from your browser.
