webp and lazy loading are so powerful that having to do things without it really feels like IE. The big difference is that IE users for some reason failed to install something better. Safari users are locked in.
Safari supports lazy image loading, which is probably what you want. Just not iFrame lazyloading, which you shouldn’t be using all that much anyway.
It also supports webp, even though I never use it. It’s a Google thing, not widely supported by image editors and which fails to be consistently better than a properly optimized jpeg.
If you thing you need webp try running it through MozJPEG first
MozJPEG is truly magical. My image editor of choice Acorn added it and I've been using it heavily ever since when I want to share a screenshot of reasonable fidelity but would rather it not be 3.8MB.
I would like to see a decent true successor to JPEG which does stuff like alpha channels, but the annoying extend-embrace-extinguish approach Google used with WebP has turned me off of considering it very seriously.
Which won’t open in Photoshop 2021, or your parents notSoSmart TV.
Questions like: will you be able to open them in 20 years, does this version of ImageMagic supports it, are not things I’d want to deal with daily.
Yeah, thanks but no thanks.
Hard to compete with standards with expired patents and equivalent if not better performance when the other side is sponsored by a single company. Especially one not particularly known for long term commitment to their projects.
I don't think webp was ever meant to be an archival format, especially when used lossily. I wouldn't want a dithered blurred png to be the one archived image I have, either.
Typically I've seen webp served at the CDN or client, where a png or jpeg alternative is also available, and where (hopefully) the website owner has the original asset somewhere safe.
Between "now" and "nobody uses webp" anymore, it's still a super useful format to speed up pages for a majority of users. That doesn't mean you should rely on it to be a safe archival medium, but that's not the only consideration.
Of course nobody is going to force you to use that (or really notice if you don't). It's just one image format out of gazillions.
