Google A few months ago, Google open sourced the VP8 video codec as part of the WebM video project, to create a truly Free/free unencumbered video format for the web as an answer to the non-Free/free patent-encumbered H264 format. Today, Google launched a new image format for the web, WebP, which aims to significantly reduce the file size of photos and images on the web.

Well they do appear in certain spots to be less noisy.

You don't get the point: The mission of image compression is to reduce the size of the image with a minimal loss of information.
You may talk about different kinds of information loss, and you may prefer some kinds of loss over other kinds of loss. But you cannot talk about improvement. Any change of the image caused by the compression technique - whether you find it improving or not - is a change, and thus it is bad.
If you want to "improve" an image, you use other techniques (sharpening, blurring, scratch detection, etc.). And then you get a new "original" that you may try to compress with different compression techniques.

Again, some images in some spots look better to me - less noisy.

I don't have to get the point of compression or image manipulation to notice improvements.
