Google's new image format

As part of its self-imposed mission to make the web faster, Google has rolled its own image format.
It’s called WebP, and it’s based on open source technology. Google launched the initiative Thursday night with a post on its Chromium blog.
WebP has much in common with JPEG, the most widely used of the web’s image formats. Like JPEG, the new format is intended to be used for photos on web pages, and like JPEG, the photos in a WebP image are compressed using lossy technology. The images will continue to reduce in quality the more you compress them.
But Google says WebP is more efficient than JPEG, and that it can shave away more than one third of the bulk in web images without any noticeable loss in quality. Google has been testing WebP’s efficiency over the last few months, taking around a million images from the web (mostly JPEGs, but also some PNGs and GIFs) and running them through the new WebP compression technology.
It says its engineers have seen a 39 percent reduction in overall file size on these test images “without perceptibly compromising visual quality,” and that it expects the results to improve once development picks up. Also, you could probably get even better results if you started from an uncompressed image.
