You need Adobe Acrobat (the full version not the reader). The latest version costs $450US for the professional version. Adobe has a trial of Acrobat 6 on their site. I'm not sure how functional the trial is but give it a try before spending the money.

edit: I just checked adobes site and they do have a cheaper version and also an online converter. They charge $9.99 per month for the online version.
