Converter for PDF file from Kindle?

I called Amazon about getting text-to-speech on the Kindle for Mac and they said it couldn't be done, but if we could convert the PDF file to put it on the computer out of the kindle app, it might work then. They couldn't (weren't allowed) to give me the name of any converters for Mac so I am wondering if anyone here knows of any converter that can be downloaded which will convert a pdf from Kindle onto the Mac. Hope this is clear!
