Wonder how this will work with random websites' photo upload features. Will all other browsers break because they are serving HEVC user-uploaded content? Or will iOS transcode to JPEG on upload (triggering double lossy encoding?)

[roywiggins]

How many websites don't already re-encode most of the JPEGs they're handed? Facebook does- Flickr does, though sometimes you can request the original file specifically. Imgur probably does.

Imgur very much does, with a visible loss of quality.

This can be disabled in account settings though.

They said you can share it as jpg. I assume it works like live photos: If the receiving app (or website) doesn't explicitely say it supports HEIF it'll receive a jpg

They mentioned you can share the photos like normal so I assume they'll do on the fly conversion.
