macOS comes with a bunch of preloaded apps that are very helpful to some users and may never be touched by others, but the one that almost everyone uses is the Preview app . Preview is a jack-of-all-trades app that can be used to view photos, documents, and has features like an editor. Advanced users may change settings and set a third-party app to open images and files by default, while casual users may only use it to view files. However, depending on what kind of user you are, you may not know the 5 hidden functions in the preview app.
5 must-use features in the macOS Preview app that you may not know regarding
Convert file type
Since the Preview app is known first and foremost as an image and file viewer, one of the most useful features in the app is file type conversion. Using Preview to convert images is not actually the fastest way, as there is a faster way to do it in Finder (right-click on the file in Finder>>Quick Actions>>Convert Image), but file conversion in Preview still Very helpful. Before doing this, you can view the file you want to convert in preview, or edit the original file before exporting:

Merge PDF files
One of my favorite tools in the macOS Preview app allows users to merge PDF files together. Some well-known PDF viewers, such as Adobe Acrobat Reader, require a subscription to put PDFs together. Many of the free options available are simple, or web-based tools that require you to upload files to a third-party server.

People often turn to third-party photo editors to remove the background of a subject in a photo, but the Preview app in macOS can actually remove the basic background from an image.
