NXPowerLite

NXPowerLite Desktop Edition compresses PDF, PowerPoint, Word, Excel and JPEG files. Files remain in their original format so no need to unzip. There is no loss of quality when files are compressed. It's really easy-to-use; you can access it from lots of places. It can optimise documents in bulk too. The best thing about it is it works with Microsoft Outlook, Outlook Express, Windows Mail or Lotus Notes, optimising files as you send them.
