Opera Turbo Uses WebP to Compress Images

Opera is probably the best browser for slow Internet connections, especially if you enable Opera Turbo, a proxy that compresses web pages. Opera 11.10 improved this feature significantly by replacing highly compressed JPEGs with WebP images.

"The most noticeable difference is probably WebP. An open standard image format that was released with some fanfare by Google last year. We thought it was about time to replace the 20 year old JPEG format with something more modern. Overall, WebP produces images with less artifacts and crisper details, even though the image takes less space," says Opera's Audun Mathias Ƙygard.

Here's an image from BBC's site in Opera 11.01 (JPEG) and Opera 11.10 (WebP):

Opera's tests showed that there's an important speed improvement: "about 22% less data transferred compared between old and new Opera Turbo". For example, BBC's science page uses 724.1 KB, instead of 1111 KB, in the old version of Opera Turbo.

There are two browsers that support WebP: Chrome and Opera 11.10, but Opera's team found a great way to use it. It's important to mention that WebP is based on WebM/VP8, a video format open sourced by Google.
