PDFshrink for Mac

From Apago:

PDF Shrink reduces the size of PDF files by optimizing the resolution and compression method of images, removing unused elements such as metadata and thumbnails, eliminating duplicate images and compressing other parts of a PDF file.

PDF Shrink can reduce most types of PDF files from 10 to 90% of their original size. PDF Shrink makes it easy to optimize PDF files for use on the web, for email attachments and for on-screen reading. The drag and drop interface allows for setting different compression and resolution choices for color, grayscale and monochrome images. Three common configurations are included; however, the user can create unlimited custom configurations. Batch processing is supported with the ability to load multiple files and folders into a processing queue. PDF Shrink simplifies the creation of optimized PDF files even further using Mac OS X's PDF Services - part of the "Save As PDF" menu in the Print dialog. Simply select "Create PDF Service" from the Configs menu and name the workflow. It\'s as simple as that. Then, whenever you create a PDF from the Mac OS X Print Center, you can automatically optimize your PDF using PDF Shrink.
