'Chrome Lite Pages' that supports data saver function that can speed up page loading speed of Chrome & reduce data usage by 90%

You need a fast web browser and a stable internet connection to enjoy the innumerable images, texts and various data on the internet. However, on mobile devices, there are cases where it takes a long time to open a page due to bad radio conditions or a large amount of data transfer. That's where the convenience comes from Chrome's data saver feature, which can increase data usage by up to 90% and page load speed by about twice. In order to clearly indicate to users whether it is a web page that supports such data saver function, " Chrome Lite Pages " have appeared.

Chromium Blog: Chrome Lite Pages-For a faster, leaner loading experience

The "Data Saver", which comes standard with the Android version of Chrome and is provided with an extension for the PC version, automatically optimizes web pages and speeds up page loading. Data saver can reduce data usage by up to 90%, and page loading speed can be nearly doubled. The data saver feature is working on improving performance on web pages that support HTTPS as well as HTTP, and Chrome's development team provides direct feedback to developers seeking performance improvements on HTTPS pages It is said that an attempt is also being made.

Chrome has announced that it has added the word "Lite" to the URL bar to clearly show users that the page is optimized for data saver. Users can tap this display to view detailed information or load the original page. In addition, Chrome seems to automatically disable Lite pages per site or per user if the user is frequently viewing the original web page instead of the data-saved pages.

Chrome Lite Pages use built-in optimization and Google server to improve page loading. The specific optimization method will vary depending on where the user is and how the developer is creating and serving that particular page. When Chrome optimizes the HTTPS page, only the URL is shared with Google, but other information such as cookies, login information and personalized page content is not shared.

The Lite page is displayed only when the page loading speed is slow at a painful level for the user, and the condition is that the connection type of the network is "2G" or "slow-2G", or First Contentful Paint It seems that it only takes Chrome to predict that it takes more than 5 seconds.

In order to try Lite page in Chrome for Android, it is necessary to enable data saver function from the setting menu of the browser. Then you can just load web pages that are very slow. When using a high-speed network, there is also a method of setting "# force-effective-connection-type" to an arbitrary 2G option from "chrome: // flag". In that case, it is necessary to enable "# ignore-previews-blocklist" so that the function is not disabled automatically.

It should be noted that since Lite pages only work on pages that are very slow to load, Google allows web page operators to know in detail how well their pages are displayed and to improve performance. We recommend using tools like Lighthouse , PageSpeed Insights and WebPageTest . It also cites web.dev as a guide for developers to learn best practices for building fast, high-performance web experiences.

Chrome Lite Pages will continue to be improved and there is an option to disable it at any time. Also, by adding "no-transform" to the Cache-Control header of the main HTML of the web page, the author of the web page can optionally invalidate the Lite page.
