Signing a PDF means adding an electronic signature to the document as a record of agreement or approval. The signature can be drawn, typed, or uploaded, then placed on the page.

Features
Draw, Type, or Upload
Draw a signature with a mouse, trackpad, or touchscreen, type your name in a signature font, or upload a scan of your real signature. Use whichever feels closest to how you normally sign.
Place It Precisely
Drag the signature to the exact spot on the page and resize it to match the line. You can drop more than one mark, which covers documents that need a signature or initials in several places.
Stays on Your Device
The document and the signature are processed locally and never uploaded. For a sensitive contract that matters, since no copy of the unsigned or signed file passes through a server.
