Google Chrome web-browser on mobile-platforms features the option to reduce bandwidth costs and enable faster web-browsing utilizing the "Google Data Compression Proxy". The same had been made available to Google Chrome Desktop users via an unofficial Data Compression Proxy extension as shared earlier, now the feature is officially made available by Google as new Data Saver web-browser extension.

Once Data Saver extension is activated on Google Chrome, the web-browser will use Google servers to compress pages you visit before downloading them. Taking user's privacy into consideration, the service will bypass the compression proxy for SSL and incognito web-pages.

Similar to Opera Turbo technology, Google Chrome features an "data compression proxy" for Android and Apple iOS mobile-devices which when enabled opens a connection between the user phone and optimization servers running in Google's datacenters relaying all non-encrypted HTTP requests over this connection. The SSL secured proxy connection performs intelligent compression and minification of HTML, JavaScript and CSS resources which are not essential to render the page. These optimizations, combined with gzip compression for all resources, DNS lookups from proxy and images converted to WebP with resulting sizes upto 80% smaller provides huge bandwidth savings and resulting in faster web-browsing experience.

This feature is not available for Google Chrome Desktop users, however a free Chrome extension now allows users to get the same savings on their desktop computers. The extension sends all HTTP (but not HTTPS) traffic through Chrome Data Compression Proxy server, which utilizes SPDY protocol to speed up web browsing. Users can check bandwidth savings by visiting chrome://net-internals/#bandwidth and can disable compression-proxy by clicking the green bolt icon from the toolbar.

Opera has always been the leader in innovating web-browser technologies and once again the Opera team has came-up with some promising stuff with public release of Opera 10.5 Pre-Alpha, the major new features worth mentioning here would be the all new JavaScript rendering engine Carakan which is touted to be 7x faster in benchmarks then it's predecessor Futhark used in current stable release of Opera 10.10, new Presto 2.5 engine with support for CSS3 transitions and transforms with more HTML5 features, new hardware accelerated VEGA graphics library and support for private tab (no need to open a window) apart from the new address-bar and other GUI enhancements.

Opera is all set to become the worlds fastest web-browser with its server-side acceleration technology to be included in upcoming Opera 10 release, the Opera team released the first public alpha of Opera Turbo demonstrating the compression technology meant for users on low-bandwidth connections, working similar to the man-in-the-middle proxy compression system used by commercial software's like ONSPEED Web Accelerator, Opera Turbo compresses network traffic providing significant improvements in browsing speeds consuming less data saving bandwidth bills.
