Google Releases Developer Preview Of New Image Format WebP

Google has announced the developer preview of WebP. What is WebP? Keep reading:

WebP is a method of lossy compression that can be used on images. The degree of compression is adjustable so that users can trade-off between file sizes and image quality. WebP files has VP8 image data and has a container based on RIFF. VP8 uses the same methodology used by the VP8 video codec.

In the Google Code developer preview, there is a download that contains WebP files (libvpx) and a command line tool (webpconv).

“Images and photos make up about 65% of the bytes transmitted per web page today. They can significantly slow down a user’s web experience, especially on bandwidth-constrained networks such as a mobile network. Images on the web consist primarily of lossy formats such as JPEG, and to a lesser extent lossless formats such as PNG and GIF. Our team focused on improving compression of the lossy images, which constitute the larger percentage of images on the web today,” stated Google Product Manager Richard Rabbat.
