Compress a PDF document with Preview

You can compress a PDF document in Preview to save space.

This process compresses the images in the document. The compressed images look the same as the originals when viewed onscreen, but they may be of lower quality when printed.

  1. Open the PDF document, and choose File > Export.
  2. Choose Reduce File Size from the Quartz Filter pop-up menu.

You can save any document as a compressed PDF file. For more information, see this help topic:
