Sign PDFs by drawing your signature with mouse, trackpad, or touchscreen. The most natural way to sign documents digitally.
Drawing your signature is the most personal way to sign a document. It's your actual signature — the same way you'd sign on paper — just captured digitally instead.
Use your mouse, trackpad, or touchscreen to draw your signature in the canvas. If it doesn't look right, clear it and try again. When you're happy with it, place it on the document.
Draw or upload your signature and place it on your PDF quickly and securely.

Drawing a signature uses a canvas interface where you create your signature by hand — using mouse movement, trackpad gestures, or touchscreen input. The drawn signature is captured as a transparent image and embedded in the PDF at the location you specify. The result is a personalized signature that reflects your actual handwriting style.
Use cases include:
Signing contracts where a personal, handwritten-style signature is preferred.
Adding your signature to official documents where authenticity matters.
Signing documents on a tablet or phone where drawing is natural.
Creating a personalized signature for regular document signing.
Signing agreements where the recipient expects a handwritten-style signature.
Your actual signature, on any document, without printing.
