This could not be simpler. You have a PDF document and you want to convert it to a Word document. Simply locate it on your computer, hit convert, and the job is done. Why would you want to do this? Sometimes you want to mark up a document with highlighers, or save it in another document. Unfortunately, if you look closely at a paragraph, it leaves a line break as that rather than treating it as simply running onto the next line. But it is free.
