Lesson 13. Distributing PDF Documents > Optimizing PDF documents

Optimizing PDF documents

Optimization consolidates and reorders your PDF documents, and in most cases, reduces their file size significantly. Acrobat removes duplicate background objects (text, line art, and images), replacing them with pointers to the first occurrences of those objects. Optimizing also reorders objects in the PDF file format for page-at-a-time downloading over the Internet. With page-at-a-time downloading (also called byte-serving), the Web server sends only the requested page of information to the user, not the entire PDF document. This is especially important with large documents, which can take a long time to download from the server.
