Chrome JPEG XL support


Those who are interested will find an introduction explaining Chrome and JPEG XL below for SEO purposes. You can jump to the tutorial on how to enable JPEG XL support on Chrome and Chrome for Android by clicking here.

What is JPEG XL?

As a professional image delivery format, the JPEG XL image format meets the needs of web photographers and web designers alike. As well as supporting wide color gamut and high dynamic range, it also supports high bit depth images. Additional features of JPEG XL include animation, alpha channels, layers, thumbnails, lossless, and progressive decoding.

JPEG XL provides a significant improvement in image quality and compression ratio compared to legacy JPEG. You can quickly transfer legacy JPEGs to the new format due to the implementation of lossless JPEG recompression.

JPEG XL allows for lossless compression and lossy compression. Typical compression allows between 20-60% reduction in file size. Using software implementations, it is possible to encode and decode in a computationally efficient manner without requiring any hardware acceleration.

What is Chrome?

Google develops and maintains its closed-source web browser called Google Chrome. Google Chrome is an excellent web browser that makes it easy to access the web from mobile devices and desktop computers because of its ease of use and flexibility. Chrome is known for its superior speed and performance compared to other browsers such as Internet Explorer, Microsoft Edge, or Firefox. In 2008, Google introduced Chrome for Windows. After that, Chrome has become available on macOS, Linux, iOS, and Android. Chrome's fans enjoy its extensive collection of extensions, its excellent performance, and its customization capabilities. Nonetheless, Chrome has received some criticism for its high memory usage and its history of tracking user data. Statcounter reports that Chrome occupies 63.5% of the global market share for web browsers. Despite Chrome's all-time high adoption rate of 72% in 2018, Google still holds a significant monopoly on the browser market.

Check your Chrome Version

What are Chrome Flags?

Since version 91, JPEG XL is available behind a flag, which means the functionality is not enabled by default. The term "flag" refers to features in development for Chrome. They are often found in a hidden settings menu that you can access through the navigation bar. Before reading the following instructions for enabling JPEG XL, we remind you that Google considers flags unstable. There is no information as to when Chrome will support JPEG XL by default. Nevertheless, it is safe to say that your browser or computer will unlikely be adversely affected once image format support is activated.
