I find this particularly annoying. Back in the early 2000s I wrote some small app to generate static webpages for photo collections to be put on CD because OSes couldn't browse jpgs natively but browsers could. Now the problem has gone the other way, my iPhone and Android save HEIF but I can't use those on the web. I have to first go through a manual conversion process. It's like my computers have regressed 20 years.
