Based on QtBug reports search, there is a bug report to add support for avif to QImage from 2025 that appears to have no work done on it. Basically it has been ignored.

There was another request to add jpeg-xl to QtWebEngine from 2024 that was also basically ignored.

So if Qt does not support jxl in QtWebEngine we are pretty much up the creek without a paddle.

Update:

From another web search ...

Google Chrome reintroduced support for the JPEG-XL image format starting in Chrome 145 (released in February 2026).The feature returned to the browser's codebase after Google removed it in 2022, but it remains hidden behind an experimental flag and is not yet enabled by default.
