Merge PDF files on a Mac

Preview, included with macOS, merges PDFs by dragging pages from one document's sidebar to another's. You can move single pages or add a whole PDF at once.

With Preview

  1. Preview saves changes automatically. To keep the original PDFs, choose File > Duplicate for each one first.
  2. Open the PDFs and choose View > Thumbnails in each of them.
  3. Drag the thumbnails you want from the sidebar of one PDF to the sidebar of the other. Command-click to pick pages that aren't next to each other, and drag thumbnails to change their order.
  4. To add a whole PDF, drag its icon from the Finder to the sidebar of the open document.
