The current MIME type for AVIF images is



Google Chrome in version 85 added support for the AVIF image format and Mozilla Firefox and Safari from Apple will not be that far behind in supporting it.

The AVIF image format provides great file size and compression gains over JPG, PNG and WebP images.

I'm on Firefox 81 beta, and I already have avif support. +1 from me, I'll submit a patch if the maintainers agree :).

I submitted a PR to PHPMailer, which apparently I includes a list of mine types. I suppose SimplePie will need an update too. After that, it will be all in core.
I don't think the image editors will be compatible with heic or avif, so adding avif/heic to those wouldn't work out well.

This ticket was mentioned in Slack in #core by yui. View the logs.

It looks like AVIF support has been added to Webkit as well: https://bugs.webkit.org/show_bug.cgi?id=207750

For now, can WordPress at least allow AVIF images to be uploaded via the Media Library?
