    What?

    In the beginning of the article you state one of the main problems with web-based PDF compressors is that they don’t allow bulk conversion – this is true, and why I landed on this article.

    Then the very first program you recommend…doesn’t support bulk compression…brilliant.

      They probably added this feature after I blog about it. Back then, it wasn’t there, I was searching for it too to bulk compress my thesis.

      it really depends on how small is the file to begin with. If the file is 10KB, dont expect much gains.
