Smaller files - same format

Optimize or Compress?

NXPowerLite now does both, so when you send your email it will try to optimize and compress and apply whichever is the most effective technique at reducing file size - in some cases both.

Reduce files - automatically

You can also selectively reduce files within your Office applications, or use the ‘NXPowerLite’ menu to quickly optimize files directly from Windows Explorer.
