Only Apple supports this. Like, literally just Apple. I hate Chrome, and even Chrome doesn’t support this. Firefox? Yeah, zero support.
So for these reasons it’s 100% not viable right now. If you get the support, I’ll consider it for my websites, and tell my colleagues about it, though.
Tell that to Google’s SEO ratings. A website using jpeg’s is not going to do well.
People just really need to support it. It’s far better than jpg or png. It’s the go-to for web right now, that’s for sure.
Share your source, otherwise this is just bullshit. I think it’s bullshit.
Edit: I don’t doubt the covid part. Maybe that causes weird reactions. It’s been described to me as “different”, rather than a loss of smell.
Edit 2: Still no source. Downvote all you want, you’re still not convincing any scientifically minded individual that you’re correct.
This is the source I used to originally validate my position: https://caniuse.com/jpegxl
Let me know if it’s incorrect, I’d be very interested to learn of new options for the web space as a developer. This said, I googled Firefox and it came back with only “experimental support” for what I think may be an alpha release (version number ends in “a”).
