Last week Jetpack announced that its Photon image service added support for the WebP image format, which provides up to 34% size reduction for served images when compared JPEG images of the same visual quality. For Photon users this translates into faster-loading pages.
WebP is not yet natively supported by all browsers, so Photon will auto-detect the visitor’s browser and serve the images in the best quality/speed possible.
I spoke with Jetpack team leader George Stephanis at WordCamp US about the improvements to Photon, and he broke it down for us in the video interview below.

So, is this done automatically or is there a hook or a filter that needs to be enabled?

Ignore me, I thought Photon converts the images automatically. That would be great!
Instead, I have to use third-party plugins to do it.

With Photon enabled images will be automatically converted to WebP (when a browser that supports it requests your image) . All you have to do is upload your images to your post or media library and Photon will take care of the rest. Note: the file extension won’t change, only the MIME type, but it is indeed WebP

Thanks @Jesse.
So I can’t actually check the source or the headers to see the change, can I? I tried with several images and they’re still JPEGs. Using latest version of everything and PHP 5.6.13.

You can use your browser inspector to check it. Here is an example with one of the images on your site:
