You can also edit PDF files with this application. Preview is the default app for viewing images and PDF files on your Mac. So, any time you double-click on, or otherwise launch, one of those files, it'll open in Preview. If, for some reason, another app has taken over responsibility for a certain file type, and you want to give it back to Preview, you make the change right in the Finder. Preview is the image viewer and PDF viewer of the macOS operating system; it enables users to view and print digital images and Portable Document Format (PDF) files. Preview uses Apple's implementation of the PDF specification, the Aqua graphical user interface, the Quartz graphics layer, and the ImageIO and Core Image frameworks.
If a PDF contains sensitive information, you can keep it secure by adding a password.
