WebP – A new image format for the Web

I'm confused what you are doing. You are taking an existing lossy format e.g. JPG and then recoding it in another lossy format. So yes you may save an insignificant amount of bandwidth but at the expense of introducing potentially significant artefacts in your images. What serious web developer is going to want to do this ?

WebP IS lossy: http://en.wikipedia.org/wiki/WebP

And as you can see from the page there are artefacts that humans can perceive.

Both the original article and the Wikipedia page state that WebP support lossy and lossless compression. I guess using lossless WebP would not make sense for JPEG files as the result would probably be bigger than the original JPEG, but it might work well with PNG.
