|convert-lzw-to-flate||Recompress LZW-compressed streams using flate.|
|optimize-page-content||Removes redundant content streams, or page text.|
|optimize-for-fast-web-view||Place all the information needed to render the first page of the document near the beginning of the file. This process is also known as linearization. This allows a web browser to open the PDF document more quickly.|
Flate, or Deflate compression, is an open source standard widely used for creating zip files and with PDF. It is commonly used for PNG image files, and is much more widely used than lzw.
Lzw, Lempel-Ziv-Welch, is a universal data compression algorithm, once widely used with Unix platforms. This method appears in some old PDF documents but it is rarely used any longer.
