Reduce PDF file size

System Requirements:    
Mac OS X 10.5 or later

What does this Automator Workflow do?
You choose one or more picture or PDF files in Finder and then Automator applies a custom Quartz Filter to the PDF(s). The output is to a new, smaller PDF file.
What is a Quartz Filter?
Quartz is the rendering engine of Mac OS X. Built into Mac OS X are special filters you can use to perform a variety of tasks. Shrinking PDF files is one of those tasks.
