1. Open PDFs
- The first thing that you want to do is to open both PDFs that you want to combine in Preview.
2. Show the PDF thumbnails.
- A tray will open on the lefthand side of Preview, showing you the individual pages of your PDFs.
3. Click and Drag the Pages
N.B. It’s important to drag the thumbnails onto the other thumbnails and not below the very thin line that appears at the end of the thumbnails. If you do the latter, you will still only have two files.
