NXPowerLite File Compression Technology

All our products use the same core technology for compressing Adobe PDF, Microsoft Office, JPEG and TIFF files without changing their file format. Download the full technology guide

How it works:


32 second technology overview video

Compared with traditional compression, File Optimization takes a different approach to tackling the problem of large files. Its remarkable performance stems from the fact that many large files, such as PDFs and Microsoft Office documents, contain a great deal of hidden bloat that can be stripped away or 'optimized' in order to reduce file size without changing the file format or affecting the visual integrity of the file.

File Optimization tackles individual elements inside a document, assessing how to reduce each component in turn. By examining each component in isolation it will choose the most effective method of reduction rather than applying general settings across the whole file. This approach creates much smaller files that remain in the same format, so no readers or decompression tools are required.

Key features

Reduces file size without changing format

File Optimization carefully targets and removes excess data from files, leaving them smaller but in all other ways identical to the originals. This ensures that file owners will not be aware of any changes to their files. Examples: Original 8.3 MB | Optimized 1.9 MB

Effective on already compressed files

Microsoft Office files are often already compressed and contain lots of pre-compressed content like JPEG images. Unlike standard compression technologies, File Optimization is very effective on these compressed files. Examples: Original 6.3 MB | Zipped 5.9 MB | Optimized 0.4 MB

Reduces photos without down-sampling/scaling

It substantially reduces the file size of JPEGs by re-encoding the image using more efficient settings without reducing the image resolution. The image remains visibly unchanged but takes up less disk space. Examples: Original 5.5 MB | Optimized 2.3 MB

How we handle files

File Optimization technology is designed to avoid negatively affecting document compliance obligations. The technology simply makes imperceptible visual trade-offs to reduce file size. The primary focus is ensuring embedded media (photos, graphics etc.) are stored in the documents efficiently while unseen background data is purged from the files. File Optimization sets out to maintain the visual integrity of the content so at all times optimized files should be indistinguishable from the originals by the human eye.

We encourage you to check the compliance requirements of your industry carefully and if there is any need for further clarification on what File Optimization does to files do get in touch.
