NXPowerLite可以把Word、Excel、PowerPoint等office檔案最佳化，也可以直接在 Windows 檔案總管中以右鍵點按執行。是一款優秀的office檔案專用壓縮工具
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. NXPowerLite Desktop Edition will automatically optimize email attachments as they are sent. File recipients don't need NXPowerLite to open or edit the attachments.

Features:
Simple user interface
NXPowerLite Desktop Edition is fast, effective and incredibly easy to use. The simple user interface will feel instantly familiar and you'll be optimising your Word, Excel, PowerPoint and JPEG files within seconds.

Email add-in
NXPowerLite integrates with your email client to automatically optimise attachments. If you ever decide that you don't want to optimise an attachment, it's easy to temporarily disable the optimisation (it will be re-enabled next time you send an attachment).

ZIP archive optimisation
You can even optimise files when they're stored within standard ZIP archives. NXPowerLite will look inside your .zip files and optimise any Word, Excel, PowerPoint or JPEG files it finds.

Choice of optimisation levels
You can optimise for screen, print or mobile devices – or select your own custom settings. Whichever you choose, you'll find that NXPowerLite is far more effective than ZIP compression on image-heavy files.

Batch processing
You can optimise multiple files in one sitting – simply drag them onto the NXPowerLite window to build a list of files to optimise. If you add a folder or standard ZIP archive to the list, NXPowerLite will search through it and optimise the Word, Excel, PowerPoint and JPEG files it finds.

Microsoft Office integration
NXPowerLite is fully integrated with Microsoft Office, so you can optimise your current file from within Word, Excel or PowerPoint. You can also optimise a file by right-clicking it in Windows Explorer.
