Combine PDFs using Preview

Combine PDF documents using Preview

  • Open the PDF documents that you want to combine in Preview.
  • Show the sidebar in each Preview window. If the sidebar is not showing, click the Sidebar button in the Preview window's toolbar, or choose View > Sidebar > Show Sidebar.
  • Verify that the sidebar is configured to show thumbnails (this the default view). If the sidebar is not showing thumbnails, choose View > Sidebar > Thumbnails.
  • Drag the thumbnail of one PDF document (source) over of the thumbnail of the other PDF document (destination) and release the mouse or trackpad button when the pointer shows a green circle with a plus symbol in it. This will copy all pages from the source PDF and add them to the end of the destination PDF.
