According to Google: “ WebP is a method of lossy compression that can be used on photographic images. The degree of compression is adjustable so a user can choose the trade-off between file size and image quality:”
SEO-ers and professional site owners have always been optimizing their JPEG images on their sites in order to augment the quality of speed. Now they can easily apply WebP format instead of JPEG.
Images and photos make up about 67.5% of the bytes transmitted per a web page. These images or pictures can slow down a user's web experience, especially on a mobile network. So Images on the web consist of loosy formats such as JPEG, and to a lesser extent lossless format such as PNG and GIF. Google focused on improving compression of the loosy images, which covers the larger percentage of images on the web today

Google is also developing a patch for WebKit to give native support for WebP. The webpconv command has the following syntax:
webpconv [-output_dir dir] [-format format] [-quality quality] input_file(s). As you see in this syntax the path is your directory where files are placed. If no path is specified, the files will be created in the input directory. The range is from 0 to 100; 100 is the best image quality with the largest file size. If no value is specified, the default quality value corresponds to a target peak signal-to-noise ratio (PSNR) value of 42. A PSNR value of 42 is usually regarded as a good quality image.
