Announcing Guetzli: A New Open Source JPEG Encoder

How long until someone makes a front-end to this that lets you preview the image at different compression rates? Or does it exist already?

Also...

> Note: Guetzli uses a large amount of memory. You should provide 300MB of memory per 1MPix of the input image.

For web images that's probably not an issue but for photos that is beefy machine.

As an aside: I love to see projects named after food in my mother tongue (guetzli is Swiss German for cookie). I guess this is a project somewhat based on the Zürich office of Googles.

Before this one we got brötli (small bread) and zöpfli (also a small bread, but a specific type), though both lost their umlauts in the transition to a software project

I wonder how the quality compares with MozJPEG?
