Web standards never sleep

As we wait for ratification/adoption of  HTTP3 news arrives of a new image format promising a 50% reduction in size compared with JPEG; AV1.

There's nothing more I can add to Daniel Aleksandersen's analysis published on ctrl.blog but to say that support is coming soon in Firefox and already available in Chrome.

When it will be available in Edge and Safari still seems a bi of a mystery - they took a lot longer to adopt webp, but since Microsoft's browser now uses a lot of Chrome under the hood, it might appear a lot quicker there.

libre-software.net has a test page with links to additional resources.

AV1 also does video.

Image compression (again)

It's not the most exciting thing to have happened to web performance in the past year or so - but it will have an impact on your performance and scalability. A team from Google have released a new JPEG compressor called guetzli. 

What's interesting about this one, is that the team were focused (oops) on the perceived image quality, rather than the measured quality, although they did also take time out to write their own image quality measurement algorithm.
