Find out if your browser supports the new JPEG XL image format
JPEG XL is a next generation image format. It has the .jxl file extension and “offers significantly better image quality and compression rates than legacy JPEG” according to the JPEG committee.
It is a royalty-free format that offers high fidelity to the source image, good encoding and decoding speeds, and lossless transcoding of JPEG images.
Browser manufacturers such as Mozilla or Google have started to implement support for the new JPEG XL format in their browsers.
Find out if your browser supports JPEG XL
A quick way to find out if your browser supports the new JPEG XL image format is to try opening a .jxl image in the browser.
I uploaded a sample image that you can access here (bonus points to identify the city on the photo).
If the image is displayed, JPEG XL is supported in the browser. If you get a download dialog instead, the new file format is not supported. The latter does not necessarily mean that the support has not yet been implemented, only that it cannot be enabled by default.
Enable JPEG XL support in Google Chrome
Google has added experimental support for the JPEG XL format to Google Chrome Canary (92.0.4503.0). It is not enabled by default and must be enabled by users before JXL images are displayed in the browser.
- Load chrome: // flags / # enable-jxl in the browser’s address bar.
- Toggle the experience status to On.
- Restart Google Chrome.
Support will be added for other versions of Chrome, Dev, Beta and Stable eventually.
Enable JPEG XL in Mozilla Firefox
Mozilla has implemented JPEG XL support in Firefox, but it is only available in Firefox Nightly (90.0a1 (2021-05-09) at the time of writing. Firefox Nightly users must enable support, as it doesn’t is not enabled by default:
- Load about: preferences # experimental into the web browser’s address bar.
- Scroll down to Media: JPEG XL and check the box next to it to enable support for the new format in Firefox.
- A restart is not necessary.
Support will eventually reach beta, developer, and stable versions of the Firefox web browser.
Enable JPEG XL support in Microsoft Edge
Microsoft Edge Canary supports the new format just like Google Chrome Canary. The feature cannot be enabled on edge: // flags at write time. Edge must be started with the –enable-features = JXL parameter to add support. That will likely change in the future, but for now, this is how it is done.
Other Chromium-based browsers will also support the new image format in the future. JPEG XL is just one image format competing to become the next standard image format on the web. Only a small number of tools and viewers support the new image format at the moment, and fewer websites are using it. There is no rush to take over the format from the user side because of this.
Now you: Does your browser already support JPEG XL? (Going through Deskmodder)
