Google says that Brotli is a “whole new data format” that squeezes in more data than other compression formats, while decompressing at comparable speeds. That should mean faster website rendering and better space utilization in most case. Brotli is as much 26% better at overall compression over Zopfli, the name of the incumbent algorithm used by Chrome.

Google also says Brotli will help mobile Chrome users experience “lower data transfer fees and reduced battery use.” Google did not say exactly when the new algorithm will start, but it did announce that the code is in ready state.
