Preview app icon

OS X has so many hidden gems that it never seizes to surprise even those who have been using it for years. One super useful feature of the Preview app allows users to add their signature to the Mac, and then quickly insert it on any PDF document. In this post we will show you how you can add your signature to the Mac and then use it to insert in any PDF using the stock Preview app. Before you begin make sure you have a pen and a paper because you are going to need them during the process.

Adding your signature to the Mac

1 ) First of all take the white piece of paper and sign on it.

2 ) Now launch the Preview app and from the menu bar click on Tools > Annotate > Signature > Manage Signatures.

3 ) On the Manage Signatures window you will find two options, ‘Trackpad’ and ‘Camera’. While you can use trackpad to enter your signature, we recommend using the camera for better results. Hit the ‘Camera’ tab and then place the signature you just made on the white piece of paper in-front of the iSight camera. Make sure the room has enough light for the camera to read the signature properly. If light is not available, try increasing the screen brightness as that would help a lot.
