If you work with documents, you frequently need to combine multiple PDFs into one on your Mac. You may want to merge several reports in a single PDF to share with clients or gather statistical info from multiple sources in one PDF for easy reference. Whatever the case, PDF merging on Mac is pretty straightforward if you have the right app.

We’ve built PDF Expert to make your PDF life easier and give you superpowers to edit PDFs the way you want. Apple awarded it as “The App of the Year” and “Editor’s Choice,” and the press praised its power and speed of work. Unlike online PDF editors, PDF Expert is safe and private as editing happens on your device and nobody has access to your files.

You can get PDF Expert for free and quickly combine two PDFs on your Mac. Easily merge either entire PDFs or specific pages. There are no limits during your free trial, so you can combine and save as many PDF files as you wish.

How to flatten PDFs before combining them

If you’d like to merge a couple of PDF forms you’ve just filled out, you need to flatten them first. This makes your form non-interactive, so nobody can change the data you entered in the form fields.

To flatten your form in PDF Expert, click File > Save as Flatten. You’ll get a flattened copy of your form and will be able to merge it with other files using one of the methods we described above.


PDF merging on Mac is a piece of cake with PDF Expert. Besides helping you combine PDF files on Mac, PDF Expert can do many other tasks for you. You can edit PDF text and images, sign documents, compress PDFs, and more.
