About the Sign PDF tool
Print the document, sign it with a pen, scan it, then send it back — an exhausting cycle for a single signature. This tool shortcuts it: draw your signature with your mouse or your finger on mobile, pick the page, position, and size, and download the signed file within a minute. Ideal for contracts, quotes, and forms that need a quick signature.
Your signature is inherently sensitive data, which is why where it's processed matters: here it's drawn and embedded into the file exclusively inside your browser, so it's never stored on any server and nobody can reuse it. Keep in mind that legal recognition of simple electronic signatures varies by country and document type, so check your jurisdiction's requirements for official documents.
