The good news is that it looks like it could be making its way onto Chrome soon. This is according to a post by Ilya Grigorik (via Engadget) who confirmed the upcoming feature. No word on when exactly it will be arriving, but it will definitely be something to look forward to, especially if you are a Chrome user.
Prior to this, Google used another algorithm called Zopfli. However Google claims that with the algorithm developed that resulted in Brotli, it was anywhere between 20-26% more efficient than its predecessor. Google had also made the algorithm public, meaning that other developers who wanted to use it could go ahead and do so.
Now as for those who do not use Chrome, there are alternative methods to compressing data. For example Opera has developed Opera Max which is another data compression tool. We can’t be sure which is more effective so we guess you’ll just have to take either for a spin to find out for yourselves.
