File optimisation

Files are often much larger than they need to be. Optimisation makes them smaller – with no discernible loss of quality.

File optimisation can dramatically reduce the size of image-heavy files – by as much as 99% in some cases. It works by eliminating any excess baggage and converting graphics to the most appropriate file format and resolution.

Optimised files remain in their original format and retain all their functionality, so they can be opened and edited by anybody. There's no need for special decompression or viewing software.

NXPowerLite is a software-based technology that can optimise Word documents, Excel spreadsheets, PowerPoint presentations and JPEG images. Independent testing has shown an average reduction of Word files by 84%, Excel files by 76% and PowerPoint files by 88%*.

Optimisation vs compression

File optimisation can reduce the size of image-heavy files far more effectively than traditional compression methods, such as ZIP compression. Optimising a large PowerPoint presentation will often reduce its file size by 90% or more (zipping the same presentation will result in a compression rate of just 10-15%). And, as optimised files remain in their original format, there's no need to unzip an optimised file before using it.

However, file optimisation can be used alongside file compression. Compressing an optimised file (or optimising a compressed file) will often make the file even smaller. NXPowerLite technology can optimise documents, spreadsheets, presentations and images stored within standard ZIP archives, so it doesn't matter whether you optimise or compress first. This means NXPowerLite can work in harmony with your existing ZIP compression tools.

Why optimise?

Optimising your files will save you time and money – whether you're using your home computer or managing the IT infrastructure of a global enterprise. Discover the benefits of file optimisation at home, at work, in business, or in government and defence.
