I don’t know if you are interested in a little extra work to convert your files,
but as long as you have PLR rights and can edit the main product, you can convert files for free
at https://www.online-convert.com/
If you have a pdf file, you can convert that to pptx here
https://document.online-convert.com/convert/pdf-to-pptx
I have converted lots of files here, even my G4 files to mp4 so I could actually
use them in a podcast or video. You can spend a little time looking through the
file possibilities, and simply experiment.
