Abstract:

Distributing documents as Adobe PDF files can reduce the problems that may occur when you exchange large presentation or page-layout files. In many cases, you can make your Adobe PDF file even more compact without compromising the document's integrity. The PDF Optimizer in Adobe Acrobat 6.0 Professional gives you easy access to several options that can help you reduce the file's size, including compression options that are comparable to the ones available when you create an original Adobe PDF file using Adobe Acrobat Distiller.
