After ignoring WebP for years, I finally decided to check it out. For a long time I thought PNG, GIF, JPG, and MP4 would be enough. Not anymore. A Little History WebP was developed by Google to create an image format for the web. A format that provides better compression, alpha channels (transparency), and even animation. When Google released WebP to the world on September 30th 2010, browser support was non-existent, and that made it near impossible to evaluate.
