 from the comments:

 Extra software is not necessarily needed on MacOS X. You can use ColorSync Utility app.

 1. Open ColorSync Utility app from Applications > Utilities
 2. Choose File > Open, then select your PDF document
 3. When the file opens, click the Filter pop-up menu at the bottom of the window, then choose Live Update from Filter Inspector. The appearance of the PDF document will then change as you select and edit a filter in the filter inspector.
 4. Create a new filter by clicking the + icon
 5. Click on the dropdown to the right of your new filter Add Image Effects > Color Image Sampling and add another Add Image Effects > Image Compression
 6. Play with the settings until you’re happy and proceed to Save As…. or Save the document itself and you’ll find yourself with a more compressed PDF version.
