Google Compression Algorithm Zopfli May Lead to Faster Internet
Google has released a new data compression algorithm it hopes will make the Internet faster for everyone.
Dubbed Zopfli, the open-source algorithm will accelerate data transfer speeds and reduce Web page load times by compressing content up to 8 percent smaller than the zlib software library, Google said in a company blog post today. Named after a Swiss bread recipe, the new algorithm is an implementation of the Deflate algorithm, which is used in the ZIP archive format, as well as in gzip file compression.
“The higher data density is achieved by using more exhaustive compression techniques, which make the compression a lot slower, but do not affect the decompression speed,” said Lode Vandevenne, a Zurich-based software engineer who implemented Zopfli as part of this 20 percent time activity.
Zopfli is a compression-only library, meaning that existing software can decompress the data. It is also bit-stream compatible with gzip, ZIP, PNG, and HTTP requests, among others
