I have been using pdfsizeopt to resize pdf files. It uses jbig2 as the encoder and the reduction in size varies. The last pdf went from 51MB to 13MB with little appreciable difference in quality.

Thanks for the reference.

Simply using GhostScript to rewrite the file took 600K from the size of the PDF document that I tried (3.2MB vs. 3.8MB, approximately).

Another thing that is good to check when *creating* PDFs, is if you are using embedded or standard fonts. pdffonts lists what fonts the PDF uses, their types, and if they're embedded. Using Times instead of Times New Roman can reduce the size by an order of magnitude for small text documents.
