Hi

Take a look at

free 30 day working demo.

Be very carefull because although not an expert in Ppoint I do use flash a
lot in web sites. Depending on how you presentatio  is formated your
converted file can end up being massive, In many cases I start from scratch
to reduce file size on the web.  As an example a well know (probably illegal
presentation) is 2.51 mb converting it to flash made it 9mb in size. Re
starting in flash created a file size of 3mb.

 Hello everybody,
 Could you please recommend a good PowerPoint-to-Flash conversion program, so
 I can place my PP presentation on a website - is it the right and the only
 way to do it?
 Thank you,
