I've been using the free program, CutePDFWriter, for some time now to convert my word processing files to .pdf format.

However, without paying for it, I've had a difficult time figuring out how to convert .pdf files back to word processing formats.

Then, with a simple Google Search, I came across this website = http://www.pdfconvertonline.com/pdf-to-rtf-online.html

It's free and simple to use.
