Export a single PDF page on Mac

You may need a piece of a PDF document for reference later.
Here is a neat little trick to get that PDF page out of the document.

  1. Open it in Preview
  2. Press Alt+Cmd+2 to show Thumbnails (or use View > Thumbnails)
  3. Drag the thumbnail of desired page to the desktop

Now you’ve got your page in a single-page PDF document.
