If you need to merge multiple PDF files into one and you have a Mac, you can easily merge multiple PDFs for free. Whether you use the software that comes with your Mac, the website, or a paid option, here's what you need to know about how to merge PDF files on any version of macOS.

The Preview program that comes preinstalled on every Mac offers a super-easy way to merge PDF files for free. Please follow these steps to merge PDFs:

  1. Open the PDF files you want to merge using Preview.

    Go to the Applications folder to find and open Preview, or press Command+Spacebar to search and launch the application using Spotlight.

  2. Click the sidebar button and then click Thumbnails to make sure the page thumbnails are visible on both PDFs.

  3. On a PDF, select a thumbnail.

    You can select all pages by clicking Command+A , or you can select individual pages by holding down the Shift key and clicking the pages you want to merge.

  4. Drag the thumbnail you selected in step 3 to the thumbnail sidebar of the target PDF.

    Choose where the new PDF appears in the merged file by dragging and dropping it to your preferred location. You can also rearrange files in the thumbnail sidebar after dragging and dropping them into the target PDF.

  5. Save the new merged PDF and rename it.

    When you drag and drop a PDF thumbnail into another PDF, the changes are saved in the target PDF.

If you have Adobe Acrobat (which is part of the Adobe Creative Cloud family of high-end graphics, animation, and publishing programs), you can use that program to merge PDFs. How to do:

You can only do this using the paid version of Adobe Acrobat. The free Adobe Acrobat Reader program cannot merge PDFs and will only prompt you to upgrade to the paid version.

  1. Open Adobe Acrobat.

  2. Go to the Merge Files section and click Use Now .

    This sequence may also appear as Merge Files > Open > Add Files .

    If this option does not appear by default, first click View all tools .

  3. Click Add Files .

  4. In the Finder window, navigate to and select the PDFs you want to merge > click Add Files .

    You can select one at a time, or you can select files that are adjacent to each other by holding down the Shift key when clicking, or non-adjacent files by holding down the Command key when clicking.

  5. All files you want to merge will be displayed. You can drag and drop them to change their order in the merged PDF. When they are in the order you want, click Merge .

  6. In the newly merged file, you can still reorder pages by clicking on the page thumbnails in the sidebar, then dragging and dropping the pages to reorder.

  7. Save PDF.
