Same holds for avif and jxl. They are very storage efficient but jpg is still the best choice for compatibility reasons. You can use jxl to annoy chrome users because they can’t view it and probably apple users as well but aoart from that fun there’s no reason to convert your whole library to it. Your devices, clients and editors have to support it. And we are still not there yet. Best is to spread the word that it’ll be the future but the future is not yet today.
