NXPowerLite Software Development Kit (SDK)

Include our file compression engine in your own applications

The NXPowerLite SDK is a collection of libraries, wrappers and interfaces that enables Windows developers to integrate the NXPowerLite file compression engine into their custom applications in a client and/or server environment. 

Using the SDK you can programmatically reduce the size of image-heavy PDF, Microsoft Office, JPEG and TIFF files. It works by eliminating any excess baggage from the files, and converting graphics to the most appropriate file format and resolution.


Get started quickly and simply

We provide code samples with the SDK for each coding language, except the C API. All languages demonstrate two examples - an optimization of a single file in its simplest form with no options set, and a more advanced sample that recursively optimizes a folder structure of files, setting options that match the screen settings of the desktop optimizer. All of the samples have pre-built binaries, and the C, C++,C# and Java (Windows)  examples have Visual Studio 2013 Solutions to help build the samples.
