Preview is one of the native apps that come preloaded on your Mac. For most users, it’s just an image viewer that allows them to open and view the many different types of images available on their Mac.
However, that’s not the case. The Preview app on Mac is capable of more than just letting you view your images. There are many features that this application is only for you if you are willing to discover and use them for your tasks.
Some of Preview’s lesser-known features include the ability to lock your PDF, add a signature to it, and even edit your images. Once you’ve learned how to use these features, you won’t need to use any third-party apps you may have installed on your machine.
