You Need Adobe Acrobat Go to Adobe's website and you can sign up to do it on line. I believe you get 5 conversions for free before you have to pay.
Depends if you need the formatting or just the text. Acrobat reader which seems to be easily available off the web enable you to highlight text and then copy paste it into a word document. Formatting layout etc has to be then doen manually but it does save a lot of typing.
PDF995 Try: www.pdf995.com Excellent piece of software that works like a printer driver. It will work with ANY program that allows printing. You get a "nag" each time the program is used (unless you pay $9.95 to register).
Use openoffice, it will open word documents, and allows you to save as PDF. http://www.openoffice.org/
