How it works
How does NXPowerLite reduce file size so significantly without affecting visual content integrity?
Files are often much larger than they need to be. This 'file bloat' is most often caused by inappropriate choice of image formats, excessive image resolution or large blocks of data unnecessary for normal use of the file.
Some of the worst file bloat offenders are Microsoft Office and JPEG files, which are among the biggest contributors to storage consumption.
File bloat is most noticeable when files are combined or embedded. For example, if a JPEG image is inserted within a PowerPoint presentation, it is almost always stored with much too high a resolution. Or pasting part of an Excel spreadsheet into a PowerPoint presentation actually results in attaching the entire spreadsheet instead of just the visible portion. Both these examples result in extensive file bloat.
File optimization attacks file bloat by eliminating any excess baggage and converting graphics to the most efficient file format and resolution. You're left with a file that looks and feels identical to the original, but is much smaller.
Optimized files remain in their original format, retaining all their attributes and visual content integrity. They don't need to be unzipped and there's no need for special viewing software - so they can be opened and edited by anybody. This makes file optimization the perfect solution for primary storage reduction.

What NXPowerLite does
File optimization is 'lossy' by design - trimming bloated elements is the only way to permanently reduce file sizes. NXPowerLite removes gratuitous, excess data from your files and makes a number of additional adjustments to optimize them:

Visual quality of optimized files
Visual content integrity
'Visual content integrity' means optimized files look identical to the originals in every way. They also retain all of their original attributes and functionality.
Using NXPowerLite's default settings, there is no visible difference between the original and optimized version of a file. The optimized version is just much smaller.
Neuxpower's primary development focus is to ensure the visual content integrity of all files. Our testers optimize many thousands of files and carefully check the results – so you can confidently reduce file sizes without concern for impairment.

Average file size reductions
- Microsoft PowerPoint presentations: 88%*
- Microsoft Word documents: 84%*
- Microsoft Excel spreadsheets: 76%*
- NXPowerLite can also optimize JPEG images.
