NXPowerLite vs WinZip

Compress image-heavy files that Zip can't handle

Everyone has tried to Zip a huge file only to find it makes little difference. Most of today’s business documents contain high-resolution images and diagrams, the majority of which come pre-compressed. As soon as you add images, Zip struggles to reduce the size of a file, as it's trying to compress content that is already compressed.

Not only that, but there's the minor time hassle of having to unzip documents that you receive and the potential security risk – the contents of Zipped archives are masked from some antivirus programs.

NXPowerLite will reduce the size of files that cannot be compressed with Zip tools like WinZip, making it the perfect alternative to existing compression utilities. It even compress files within Zip files!

How NXPowerLite Works

NXPowerLite and its Optimisation technology looks at the problem a different way. Its remarkable performance is based on the fact that most Microsoft Office documents contain a vast amount of unnecessary information.


NXPowerLite tackles the individual elements inside a document, figuring out how to reduce each component in turn.  It strips out redundant material, and shakes unneeded bytes out of graphics and objects – slimming a file down rather than compressing it. In many cases it's able to reduce files by 95% with no discernible reduction in image quality.

Advantages Over Zip


Huge reduction, same file format

NXPowerLite focuses on images and image-heavy documents, and as a result can achieve far better reduction than traditional compression – typically an extra 50-75%. In addition, it leaves files in the same format – so a PDF remains a PDF. It will look and feel identical to the original, just much smaller.

What if I need to zip files?

NXPowerLite can zip files as well as optimize them, and it has also been possible since Windows XP to zip directly from Explorer, without using additional applications. Simply select one or more files, right-click then choose: Send to > Compressed (Zipped) folder.

Automatically compress email attachments

NXPowerLite integrates with Microsoft Outlook, Windows Mail and Lotus Notes to automatically reduce attachments as they are sent.  Because optimized files remain in their original format, recipients don’t need NXPowerLite to view or edit the file.

Files are kept secure

As your files are kept in their original format they are able to be scanned by antivirus software, reducing security issues you might otherwise incur with Zipping.

Best Of Both Worlds


NXPowerLite and Zip work differently and as a result complement rather than compete with each other. Choose the right method for the job and you can shrink almost any file, regardless of its content.

When to use NXPowerLite

NXPowerLite is particularly effective at shrinking images found in PDF and Microsoft Office files, as well as standalone JPEGs, because they are already compressed.

When to use Zip

Zip is good at long strings of characters in text-based Word documents or data-heavy Excel files. It’s also great for combining files into one easy-to-manage archive.
