  • pdfsizeopt

    PDF file size optimizer

    The big restriction is that the classic Postscript typefaces are not available (no Times, Helvetica, or Zapf Dingbats), and the PDF file must bundle any fonts it uses.

    The pdfsizeopt package will make any PDF smaller, and I think it deletes letters/characters from the included font that are not used.
