A new (slow) open source JPEG algorithm makes images 35% smaller and looks better than older compression systems

Guetzli is Google's new free/open JPEG compression algorithm, which produces images that are more than a third smaller in terms of byte-size, and the resulting images are consistently rated as more attractive than traditionally compressed JPEGs. It's something of a web holy grail: much smaller, better-looking files without having to convince people to install a plugin or browser makers to support a new file-format. (more")
