Indeed. In one project where I converted jpegs to webp I saw around 70% savings at similar quality. This was on Android where it's fully supported. On the web pretty much only Chrome supports it, I'm not sure why Firefox, IE and Safari are hesitant.

This [1] is from 2013, so I don't know how it holds up, but I found it in the criticism section of the Wikipedia article for webp [2].

edit: This [3] is a follow-up from 2014 to the article/study from 2014.

TL;DR: "We consider this study to be inconclusive when it comes to the question of whether WebP and/or JPEG XR outperform JPEG by any significant margin. We are not rejecting the possibility of including support for any format in this study on the basis of the study’s results. We will continue to evaluate the formats by other means and will take any feedback we receive from these results into account."

I've heard that Safari (10) on upcoming iOS 10 supports webp. Don't know about Safari 10 on macOS Sierra.

Where did you read that? Since Apple has yet to commit on H.265, ( Due to Insane patent Licensing payment ), I am hoping they jump onboard with Open Media Alliance.
