Create and use signatures

To sign PDFs, you can capture your signature using your trackpad, the built-in camera on your Mac, or your iPhone or iPad.

1. In the Preview app on your Mac, click the Show Markup Toolbar button (if the Markup toolbar isn’t showing), then click the Sign button .
2. If you want to use an existing signature, skip to step 4.
3. Do one of the following:
   • Create a signature using your trackpad: Click Trackpad, click the text as prompted, sign your name on the trackpad using your finger, press any key, then click Done. If you don’t like the results, click Clear, then try again. If your Mac has a Force Touch trackpad, you can press your finger more firmly on the trackpad to sign with a heavier, darker line.
   • Create a signature using your computer’s built-in camera: Click Camera. Hold your signature (on white paper) facing the camera so that your signature is level with the blue line in the window. When your signature appears in the window, click Done. If you don’t like the results, click Clear, then try again.
   • Create a signature using your iPhone or iPad: Click Select Device to choose a device (if more than one is available). On your device, use your finger or Apple Pencil (on iPad) to sign your name, then tap Done. If you don’t like the results, tap Clear, then try again.

If you use VoiceOver, the built-in screen reader on Mac, you can add a description of a signature when you create one. This is especially useful if you create multiple signatures and need to distinguish between them to ensure you use the intended signature. Before you click or tap Done, click the Description pop-up menu, then choose a description, such as Initials, or choose Custom to create your own description.

If you use iCloud Drive, your signatures are available on your other Mac computers that have iCloud Drive turned on.

Delete a saved signature
