You may occasionally encounter the situation that PDF documents require your signature via email whether in life or at work. It can be a tedious and nettlesome work if you have to download the PDF document, print it out and find a pen to finish the signature, then scan the signed PFD document paper and send it back. Lucky for Mac OS users, you don't need to do so to waste time and ink. Here we will introduce two methods to sign the PDF documents directly on Mac.


Sign A PDF Document in Preview


The first method is to sign the PDF documents with the Preview. You can capture your signature using your trackpad or a camera on your Mac to reuse in PDFs. Here are the detailed steps:

 

● If your Mac has a Trackpad


1. First of all, open the PDF doc that needs to be signed in Preview. Right-click on the file and choose Open With → Preview.

3. Click Create Signature when appearing a drop-down menu below the Signature button.


4. Select the Trackpad, if this option is available.


5. 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)

6. Click image.pngagain. This will open a drop-down menu with all the signatures you've saved previously.


7. Click and drag the signature onto the document. Use the mouse or TrackPad to the place where you want the signature to go. (You can click and drag the blue dots in the corner of the signature to resize the signature image)


8. Click File on the menu bar in the upper-left corner of the screen then click Save to save the PDF with the signature.

 

Thanks to the MacBook's excellent trackpad, you can sign on the trackpad with one finger and then go to preview. On the new MacBook with the Force Touch trackpad, it's even pressure-sensitive, allowing for more accurate signatures. It's even pressure-sensitive, allowing for more accurate signatures.
