Google launched Zopfli Compression Algorithm, a new open sourced general purpose data compression library.It is a new deflate compatible compressor that was inspired by compression improvements developed originally for the lossless mode of WebP image compression. Being compatible with deflate makes Zopfli's output compatible with zlib. It uses a different and more effective algorithm to compress data that can compress web content about 3-8% smaller compared to zlib at maximum compression....
