Brotpfli uses the highly optimized Brotli and Zopfli (by Google) to generate the .gz and .br archives corresponding to each of your files.
.gz and .br files can be used by web servers (for example: Nginx) to increase page loading speed, improve page indexation, and spare some bytes for the planet.
Brotpfli only creates .gz files if they are smaller than the original file.
Brotpfli only creates .br files if they are smaller than both the original and the .gz files.
Built with XML, using FileMill.
