Mozilla Announces New JPEG Encoder

Mozilla, the non-profit organization behind Firefox browser and several other open source projects, has announced a new JPEG encoder. This new project, mozjpeg, is aimed to develop a better encoder for JPEG images. The current version of mozjpeg results up to 10% file size compression.


The mozjpeg project is a fork of libjpeg-turbo with addition of ‘jpgcrush’ by Loren Merritt. Mozilla hopes it to be a significant improvement for the JPEG images, as JPEG is the most popular image file format over the web. There have been several ambitious projects, like WebP, for long but the fact is that JPEG still rules the web. As the graphic content is a major fraction of the bandwidth used by web pages, JPEG needs a boost like mozjpeg.
