NXPowerLite is a software that compresses files efficiently, including PDF, JPEG, and Microsoft PPT, Word, and Excel formats. Files stay in their original format and are easy to email, even those that can't be zipped.

This software is especially effective for files that don't zip well. Optimized files stay in the same format they were originally – a PDF remains a PDF. The best part? The compressed file will look and feel identical to the original, while being significantly smaller in size.
Optimizing files and attaching them to a new email has never been easier. Simply select the files you want to send, use 'Optimize and email' in Finder, and voila! Your files will be compressed and attached to a new email automatically.
NXPowerLite is also versatile, with registration keys that work for both Mac and Windows versions. This means that if you switch platforms, you can keep using NXPowerLite without having to purchase a new license. The multi-user license also allows you to avoid specifying how many platforms you want up front.
Overall, NXPowerLite is the perfect solution for anyone who regularly sends large files via email. Its compression capabilities will save you time and hassle, while ensuring that your files retain their original format and quality.
