Apago releases version 4.5 of PDF Shrink
Long-time player in the PDF game, Apago has released the latest update of their product, PDF Shrink. It has the ability to reduce the filesize of most PDFs, such as those from Mac OS X’s iLife and iWork applications.
Apago are targetting this app specifically for those where bandwith and storage capacity is a high priority, such as when using an iPhone or iPod touch.
How it works is to compress the images, text, fonts — as well remove unused clutter such as metadata and thumbnails. It also provides the option to encrypt your text as well.
