If you don’t want to type your name as a signature - or can’t - there’s a way to add your hand-written autograph using Preview on a Mac. All you need are a piece of paper, a pen, and your webcam.
- Sign a blank piece of paper
- Open any PDF in Preview
- Click the toolbox icon
- Click the signature icon
- Hold the paper to the camera
- Click "Done" after the signature is captured
- Insert your signature where appropriate
Preview will save your signature so you can use it on any document in the future, too!
