How to merge PDFs using Preview in macOS Monterey

If you need to merge multiple PDF files into a single document, the easiest way is to use macOS Monterey's Preview app. Here's how it's done.

Combining multiple PDF files is useful for users who have a series of forms that often need to be printed or emailed together. We'll demonstrate how to do this using Preview, the default PDF viewer.

For convenience, we will name each PDF file in the example. Our Lighthouse PDF will be called PDF A, and it will serve as the file to which we want to add another PDF. Our African Wildlife PDF file will be named PDF B and "donate" its pages to our new merged PDF file.

When you merge your PDFs together, we recommend placing your PDF A version on the left side of the screen and your PDF B version on the right side of the screen, and follow these steps operate.
