Mozjpeg 2.0 Improves JPEG Encoding

Mozilla released version 2.0 today of Mozjpeg, its JPEG encoding library based on libjpeg-turbo.

Mozjpeg remains focused on improving the compression ability for JPEG images while maintaining compatibility with existing decoders. Today's release of mozjpeg 2.0 yields an average of a 5% reduction in file-size for baseline and progressive JPEGs compared to upstream libjpeg-turbo library. Mozilla also shared that Facebook is now experimenting with mozjpeg and have begun providing some funding to this open-source JPEG encoding project.

Mozjpeg 2.0 also offers other JPEG encoding improvements as documented at length via the Mozilla Blog.
