Preview is one of the long-standing apps on macOS, having been included with the operating system for decades. In 2025, Preview finally moved over to iOS 26 and iPadOS 26, with a version tailored for mobile devices.
It is also a severely underrated app, as it is chiefly used as a way to view images and PDFs on the Mac. It’s a lightweight viewer that saves you from needing to open other heavier applications, like Photoshop or Adobe Acrobat.
