Two main ways to optimize the the exiting PDF files

1. Reducing the file size
2. Linearizing the PDF file for fast web view

We can use Advanced PDF Tools to remove redundancy or unnecessary objects from the PDF file and recompress data stream ( a sequence of data points or values) to reduce the file size, and also to linearize the PDF file.

Optimize For Fast Web View

Fast Web View restructures a PDF document for page-at-a-time downloading (byte-serving) from web servers. This option compresses text and line art, regardless of what you have selected as compression settings on the Images panel. This makes for faster access and viewing when downloading the file from the web or a network. With page-at-a-time downloading, the web server sends only the requested page, rather than the entire PDF document. This is especially important with large documents that can take a long time to download from a server.

Check with your web master to make sure that the web server software you use supports page-at-time downloading. To ensure that the PDF documents on your website appear in older browsers, you may also want to create HTML links (versus ASP scripts or the POST method) to the PDF documents and keep path names--or URLs--to the files at less than 256 characters.

How to Optimize your PDF files with Advanced PDF Tools?

Advanced PDF Tools (GUI version) provides many settings for reducing the size of Adobe PDF files. Whether you use all of these settings or only a few depends on how you intend to use the files and on the essential properties a file must have. In most cases, the default settings are appropriate for maximum efficiency--saving space by removing some embedded fonts, compressing images, and removing items from the file that are no longer needed.

Before you optimize a file, it's a good idea to audit the file's space usage to get a report of the total number of bytes used for specific document elements, including fonts, images, bookmarks, forms, named destinations, and comments, as well as the total file size. The results are reported both in bytes and as a percentage of the total file size. The space audit results may give you ideas about where best to reduce file size. You'd better experiment with various settings before making changes that can't be discarded.
