Find out if your browser supports the new image format JPEG XL

JPEG XL is a next-generation image format. It has the file extension .jxl and "offers significantly better image quality and compression ratios 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 makers 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 of finding out if your browser supports the new image format JPEG XL is to try and open a .jxl image in the browser.

I have uploaded a sample image which you can access here (bonus points for identifying the city in 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 support has not been implemented yet, only that it may not be enabled by default.

Enable JPEG XL support in Google Chrome

Google added experimental support for the JPEG XL format to Google Chrome Canary (92.0.4503.0). It is not enabled by default and needs to be enabled by users before JXL images are displayed in the browser.

  1. Load chrome://flags/#enable-jxl in the browser's address bar.
  2. Switch the status of the experiment to Enabled.
  3. Restart Google Chrome.

Support will be added for other Chrome versions, 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. Users of Firefox Nightly need to enable support though as it is not on by default:

  1. Load about:preferences#experimental in the web browser's address bar.
  2. Scroll down to Media: JPEG XL and check the box next to it to enable support for the new format in Firefox.
  3. A restart is not necessary.

Support will reach Beta, Developer and Stable versions of the Firefox web browser eventually.

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 though at the time of writing. Edge needs to be started with the parameter --enable-features=JXL to add support. This is likely going to change in the future, but for now, this is how it is done.

Closing Words

Other Chromium-based browsers will support the new image format as well in the future. JPEG XL is but one image format that is competing to become the next standard image format on the web. Only a small number of tools and viewers support the new image format right now, and fewer websites use it. There is no rush to support the format on the user side because of that.

Now You: does your browser support JPEG XL already? (via Deskmodder)

      Well it is a bit difficulty to distinguish between domains and files for instance.

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.
