File Compressor for Mac and Windows

Trusted by 3+ million happy customers

“The NXPowerLite app has become a right arm, a tool I simply could not do without, it’s the best file compressor money can buy and total value for money. The developers ensure the app is updated, and I’ve migrated from Windows to Mac and it works perfectly on both platforms. Great stuff!!!”

File Compressor Features

Trusted file compressor software

NXPowerLite was first released in 2001 and the software has been regularly improved ever since. It is super-reliable and backed by incredible support.

Official Adobe® PDF Technology

NXPowerLite uses the official Adobe® PDF Library, the same technology that Adobe® use to build Acrobat®. This library provides the perfect strong foundation for our PDF compression.

File compression software for Windows and Mac

Compress files on your local computer — it's 100% offline software. Compress files directly from Explorer or Finder using the right-click menu options.

Avoid Split & Merge

Avoid having to split and merge large files in order to send them, compress files instead and keep your documents small and intact.
