Want to convert .pdf into .swf(as3) file

Inkscape (inkscapedotorg(free) can generally take in any pdf and save it as a format you can use in flash. I don't know if the .eps works with flash, but it's the best one for converting to Illustrator. The only think to worry about usually is if you have particular fonts in the pdf that aren't installed on your machine. You can usually find out which ones they are in Adobe reader's properties menu for that document.
