NXPowerLite Desktop Edition radically reduces the size of Word documents, Excel spreadsheets, PowerPoint presentations, JPEG images and PDF files. 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 optimization level and click the 'Optimize' button. If you use Lotus Notes, Microsoft Outlook, Outlook Express or Windows Mail, it's even easier. NXPowerLite Desktop Edition will automatically optimize email attachments as they are sent.
