2) On some versions of macOS, both PDFs may open in a single Preview window, and in some, both PDFs may open in two separate Preview windows.

  • Both PDFs opened in the same window: Drag the second PDF thumbnail in the sidebar over the first PDF thumbnail in the sidebar, then release your mouse. You should see a green + icon on your cursor as you drag, indicating that you’re ready to release.

  • Both PDFs opened in separate windows: Select all by pressing Command + A or just a page from the secondary PDF file’s sidebar, and drag the thumbnail over into the sidebar of the original PDF file. When you see the green + icon on your cursor, you can let go of your mouse, and all or the selected pages will be transferred to the original PDF file.
