Over the years I’ve tried a few tools for converting from various file formats to PDF. Fortunately, I chanced upon this one:

What a great tool! All you need do is install it and it shows up as a printer that you can print to. Simply print from any application and a popup dialog box will ask you where to save your PDF file. You needn’t worry about spyware or malware either. It’s certified spyware free by CNET.
Take a look at the terrific job it did on my Math paper about Prime Constellation Counting Functions.
