PowerPressed is a plug-in for Microsoft PowerPoint.
It allows you to reduce the size of your presentations by compressing them (up to 95%), which makes them easier to handle, store or share on line. It is then possible to compress a 20 MB presentation of 20 MB to 1MB without any quality loss.
The program fits perfectly into Microsoft PowerPoint, and if you would like to try it , just download the demo version. PowerPressed runs with Windows 2000, XP and 2003.
