Depending on whether the PDF is formatted as image only, or image plus text you may find the best route is simply to run it through some OCR software
You probably have something that came with your printer/scanner - Omnipage or similar.
The supposed special programs to extract text from PDFs are often scamware product (Foxit is OK as long as you decline the toolbar...)
