About Sign PDF
The easiest way to sign a PDF online without printing, scanning, or installing software. Draw your handwritten signature directly on screen with mouse or touch, type your name in elegant script fonts, or upload an existing signature image. Place and resize the signature on any page of your PDF, then download the signed document instantly. Everything runs 100% in your browser — your document is never uploaded to any server.
What is Sign PDF?
Signing a document used to mean printing it, signing with a pen, scanning it back in and emailing it — a slow round trip just to add one signature. Sign PDF lets you place your signature directly onto a PDF on screen, so you can sign a contract, form or agreement and send it back in minutes, without a printer or scanner anywhere in sight.
Everything happens in your browser, so the document you are signing is never uploaded. You add your signature where it belongs, position and size it, and download the signed PDF. It is the practical, paperless way to handle the signatures that keep showing up in everyday work and life.
Key features
Place your signature anywhere
Drop your signature exactly where the document needs it — a signature line, a date field, initials in a margin — and move or resize it until it sits right.
No print-and-scan
Skip the entire printer-and-scanner detour. You sign on screen and download a finished PDF, which turns a half-hour errand into a one-minute task.
Signed file stays private
The signing is done on your device, so a sensitive agreement is completed without being uploaded — the only thing that leaves is the signed file you choose to send.
Standard PDF output
The signed document is an ordinary PDF that opens and prints normally everywhere, so recipients see your signature in place with no special viewer.
