Ghostscript pdf optimizer
pdfopt [ options ] input.pdf output.pdf
pdfopt uses gs(1) to convert the Adobe Portable Document Format (PDF) file "input.pdf" to a so-called optimized form in "output.pdf". Optimization puts the elements of the file into a more linear order and adds "hint" pointers, allowing Adobe's Acrobat(TM) products to display individual pages of the file more quickly when accessing the file through a network.
Note: input.pdf and output.pdf must not be the same. If they are, the file will probably be destroyed. pdfopt currently does not check for this.
Run "gs -h" to find the location of Ghostscript documentation on your system, from which you can get more details.
