Chrome To Save Data With Brotli Compression

Chrome To Save Data With Brotli Compression on Freepps Top Blog

Mobile browsing is always a test for your data plan. It’s very easy to max it when you read page by page and use browser instead of social service apps for full view. Users had to turn to third-party solutions like Opera Mini to save traffic though it brought some inconveniences.

Now a major change is expected, and the new Chrome update will bring a new compression mechanism. This will be extremely useful for the mobile version.

Ilya Grigorik, a Google developer, announced this new feature on his Google+ page. According to his information, the new algorithm will be named Brotli and will provide more than decent compression level. Your data will be compressed even tighter than a classic Gzip algorithm can.

As Google has found out in the studies, a simple HTML code will take about 25% less data to transfer, CSS tables about 20% and different JavaScript elements about 17% less than other compression methods provide. So the resulting difference will be very noticeable.

The compression will cause lower traffic consumption and battery use, so smartphones and tablets will last longer on one charge.

Unfortunately, Brotli is designed to work with HTTPS connection only. This restriction is not fatal, as most sites you have to visit from your phone may use HTTPS. But this specific feature will guarantee more security and correct work.

As of now Brotli is in beta status and is only available for Chrome Canary project users. To activate it you have to enter chrome://flags in the browser. So you can test whether Brotli allows downloading big files efficiently, how correctly it works with passwords, whether it removes critical elements of web pages and so on.

Brotli algorithm is open-source, with source files published on GitHub.

There are much wider options of implying Brotli than only Chrome, software engineer Zoltán Szabadka says. Since Brotli was announced in September, Google has found some more spheres for its implementing. For example, it’s supposed to become a part of all major browsers, no matter desktop or mobile.

This feature will be especially useful in countries and regions that follow the progress slowly and still can’t provide decent LTE or even 3G coverage.

By the way, the name is as tasty as Google tradition suggests. It’s following the preceding algorithm’s name Zopfli and means a kind of Swiss condiment, literally translated as “small bread”. So it's not only Android that sounds sweet, as you can see.
