Brotli is a new standard that provides better compression than gzip - it's now supported in all major browsers.
Brotli Compression (nopcommerce)

Checking the top 1000 URLs on the internet, brotli performance is:

    14% smaller than gzip for JavaScript
    21% smaller than gzip for HTML
    17% smaller than gzip for CSS

In 2015, two engineers at Google designed a new compression algorithm called Brotli that can have a better compression without spending more time. Brotli is already supported by the most browsers such as Google Chrome, Mozilla Firefox, Opera, and Microsoft Edge.
