PdfCompress a Reduce the size of your .pdf documents. PdfCompress is a Mac OS X utility for reducing the size of PDF files. The PDF files produced by Mac OS X‘s Quartz rendering system are beautiful, but huge, and therefore often not usable for posting on the web or sending via e-mail.
The reason for these gargantuan file-sizes is that Quartz doesn’t compress photographs and other pictures using the efficient JPEG photo compression method, instead using a different method that only yields good results for line art.
