The creators of JPEG XL say the format can bring major changes to the popular JPEG such as large bandwidth savings and higher fidelity image quality with no conversion necessary -- JPEG XL still be read as a traditional JPEG.
My name is Kelly Thompson, and I'm a VP at 500px. Buried in Tuesday’s announcement of Google’s Android Oreo was an interesting tidbit for photographers: like Apple the year before, Google’s mobile OS has been reworked to support deep and wide color, and, for the first time, full color management for Android devices.
In an attempt to speed up its sizable network and lower costs, Facebook recently decided to begin using Google's WebP image format. The format was designed by Google as a space-saving alternative for PNGs and JPEGs. WebP provides lossless and lossy compression, support for an alpha channel, support for animation and more -- all at much smaller sizes and almost identical image quality.
But all of these advantages come at a price, support for the WebP image format outside of your browser is far from universal. Google set it up as a Web format that, for now, is not supported by any of the major operating systems natively. And so, after the switch, when Facebook users tried to download a funny photo or the vacation pics their friends decided to share through Facebook, they wound up with un-viewable WebP files.
Google unveiled a new image format today called WebP that it hopes will make the web faster by cutting files sizes of images without affecting quality. According to a blog post they published earlier today, photos and images account for 65% of the bytes transmitted by websites. In their tests done using 1 million randomly selected images from the web, re-encoding images as WebP resulted in an average file size reduction of 39%. Here's a gallery with image and file size comparisons.
