The easy segment contains lot of disparate signals and can be compressed more than the difficult one, which will be assigned more bits. In this example, the encoder only used two segments. By using even more segments (up to four), WebP is now able to retain many of the original PSNR may be degraded, but the overall visual quality is much improved.

We’ve added simple encoding and decoding example binaries to the Google Instant Previews now store images in WebP to reduce their storage needs.

Users that want to manipulate WebP images can now do so using software developed by the community including Java VP8 decoder. The open-source community has also contributed support for Mac OS X with Gentoo packages and the Apache HTTP Server. On Windows, users who want to view WebP images natively, can download the PNG source, and http://commons.wikimedia.org/wiki/File:A_storm_at_Pors-Loubous.jpg
