is there a convert tool for this?

[Karen Lewellen]

Hi All,
I am taking a class on investigative journalism.  the course uses a number 
of PowerPoint presentations that are provided in pdf format.
Just to be sure I am using the most flexible method for converting these 
to something else, I am wondering if there is a tool specifically for this 
format?
Say an unpowerpaint or something?
Thanks much,
Kare
