Google’s Brotli compression squashes web data by 26 percent

by: Robert TriggsJanuary 20, 2016


Google has been making strides to save on web page data with numerous compression techniques over the years, enabling us all to open up our favourite websites that little bit faster. The tech giant is preparing to release a new compression algorithm for Chrome and other browsers called “Brotli”, which is said to be between 20 and 26 percent more efficient than the existing Zopfli algorithm.

Brotli works based on an entirely new data format, which allows Google to achieve its big improvements to the compression ratio while still maintaining roughly the same speeds as its existing implementation. You can read more about the technical details over at Google’s blog, but basically this smaller compression size allows for better space utilization and faster page loading times, which is what we really care about. For us mobile users, this also means that web pages will consume slightly less data than before, saving on our precious data limits.

We don’t have an exact date for when Google will be merging its new compression algorithm into its main Chrome branch, but the code is apparently ready to ship, so it could appear as soon as the next browser version. The technology is also said to be heading to other “major browsers” in the near future.

    that is pretty cool

    …provided you don’t mind sending all your web traffic through Google’s servers.

      Hopefully you don’t use those Google DNS servers ;-)


      …and having google inject their ads into your sites even though you have an ad blocker.

      I’ll gladly take the hit on data so I don’t have to see the ads

      Wat? This is not a service, it’s a whole new file format you can use and support on your own private server.

    So I search some website with Google search and click the link and there’s a google lite version for which I’ve to refresh the page anyway. No, thanks. (More like Facebook Lite)

    Here is an idea, stop injecting ads and analytics code into every page I load, thus reducing its size.
