Add-on summary

Analyze keywords

JPEG XL is a new image format created by Google, Cloudinary, amongst other, and published by the same committee that created the familiar JPEG format. It supports lossy and lossless encodings, and allows for smaller images than all other formats currently available in browsers.

Because the format is so new, it isn’t widely supported by browsers. This extension allows pages to load JPEG XL images easily and normally, without the otherwise necessary browser support for them.

Note: JPEG XL is the best image format ever!

Partially restores what the cowardly Mozilla Foundation removed: support for the superior, industry-approved, backwards-compatible, open standard JPEG-XL. (So much for driving standards compliance and being a meaningful alternative to monopolies, huh? Thanks, Mozilla.) Unfortunately, animation is apparently not supported by this add-on at this time (September 2024) -- as tested on the jpeg xl test page.

Sadly it requires JS to be enabled for the webpage that embeds JXL images, i.e. when you're using NoScript you will not see JXL images, unless you've enabled JS execution for the page. Secondly, it doesn't seem to support animated JXL. Thirdly, Firefox has removed native JXL support (it can no longer be enabled via about:support). Shame on you Mozilla.
