NXPowerLite Desktop Edition 6.0.8 (15th April 2014)
We are pleased to introduce NXPowerLite Desktop 6, the first full edition of NXPowerLite on a Mac.

PDF, PowerPoint and JPEG file reduction
Better reduction than in any previous version of NXPowerLite and the ability to reduce more file types.

Full support for Microsoft PowerPoint 2013 files
NXPowerLite gets amazing reductions on file sizes even with the latest version of Microsoft PowerPoint. It supports processing of all versions of Microsoft PowerPoint from PowerPoint 97 to PowerPoint 2013, including all the versions made specifically for Mac OS.

Replace original file or create a new optimized copy
The option to replace the original file rather than creating an optimized copy, was one of our most frequent requests. 

Right-click finder options

We've included a range of right-click options to Finder to make popular tasks easier and faster. For example, if you select five photos, right-click and choose 'Optimize and email', all five images will be optimized and automatically attached to a new email.

Easy to use interface
We have built on our experiences of many previous versions of NXPowerLite for Windows and bring to the Mac an intuitive and seamless user experience.
