NXPowerLite Desktop Edition radically reduces the size of Word documents, Excel spreadsheets, PowerPoint presentations and JPEG images. Files remain in their original format, with no discernible loss of quality - and there's no need to unzip before using them. It's incredibly easy to use. Simply select a file, choose your optimisation level and click the 'Optimise' button. If you use Lotus Notes, Microsoft Outlook, Outlook Express or Windows Mail, it's even easier.
