Fill out and sign PDF forms in Preview on Mac

1. In the Preview app on your Mac, open the PDF form.

2. Click a field in the form, then type your text.

If a PDF won’t allow you to type directly into the form, you can add a text box instead. Click the Show Form Filling Toolbar button , then click .

With macOS 14.2 or later, you can use enhanced AutoFill to fill in PDF forms with names, addresses and other contact information.

1. In the Preview app on your Mac, open the PDF form.

2. Do one of the following:

   • Click the AutoFill Form button next to the message “AutoFill can assist with filling out this form”. (This message might not appear if you’ve previously edited the PDF.)

   • Click a field in the PDF form.

3. Click your name in the pop-up menu that appears. Matching contact information is filled in from the Contacts app. See Set up your My Card in Contacts on Mac.

   To enter another person’s information, click Choose Other, click the person’s name, then click any detail in their contact information.

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.

4. Click the signature you want to add to your PDF. (If you used VoiceOver to add descriptions of your signatures, VoiceOver reads the descriptions as you navigate the list of signatures.)

5. Drag the signature to where you want it, then use the handles to adjust the size.

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

1. In the Mail app on your Mac, double-click a PDF attachment to open it in the Preview app .

   Note: If the PDF opens in a different app, close the file. Control-click the icon, choose Open With, then choose Preview. See Choose an app to open a file.

2. Fill out the PDF or make other changes, such as signing it or adding notes.

3. Choose File > Save, then select Reply to [Sender] or New Mail Message.

   An email opens with the PDF already attached.

1. In the Preview app on your Mac, click the Show Markup Toolbar button (if the Markup toolbar isn’t showing).
