If you are looking for how to combine pdf documents on mac, the built-in macOS PDF viewer provides a quick, free, and simple way to merge multiple PDF files into one document without installing additional software.

How to Combine PDF documents on Mac

Step 1: Open the first PDF file.

Step 2: Enable the thumbnail sidebar by clicking View → Thumbnails.

Step 3: Drag and drop the other PDF files into the thumbnail sidebar.

Step 4: Arrange the pages in the desired order.

Step 5: If necessary, rearrange the pages by dragging the thumbnails.

Finally, click File → Save to save the merged PDF file.

The entire process usually takes just a minute or two. For users who want to merge PDF documents on a Mac without using third-party apps, Preview is a convenient solution.

Pros

  • Pre-installed on macOS, operates completely offline, and protects confidential PDF content
  • Allows you to freely reorder pages before saving
  • No watermarks and no hidden feature restrictions

Cons

  • Original PDF files may be automatically modified; lacks a dedicated one-click merge button
  • Cannot directly process password-protected or encrypted PDF files
  • The workflow for batch merging a large number of PDF files is relatively cumbersome
