Adding your signature to PDFs and Images using Apple's Preview

App of the Month: Digitally Sign Documents with Apple’s Preview

Apple has made some changes to their old PDF standby, Preview.  If you’ve used it before you know it’s a great app to view PDFs and images on your Mac.  But recently they made some cool changes and the coolest is that you can EASILY add your signature to a PDF.

Now you can either use your finger to write your signature on your laptop’s trackpad OR you can use your computer’s webcam to take a picture of your paper written signature.  You can then add it easily to any PDF or Image.

Check out how it works!  I think you’ll love it.


Even though your computers are secured with logins and passwords, you may wish to delete your signature after each use to be sure that no one else can use it if they gain access to your computer.
