Mozilla introduces efficient JPEG encoder




Mozilla has a more efficient encoder for JPEG images is introduced. The encoder is compatible with existing decoders and graphics would make. Averaging five percent smaller Facebook has been conducting experiments with the new encoder.

Mozilla T-Rex logo Both images according to the stored baseline and through the progressive JPEG format are an average of five percent smaller, promises Mozilla. Many pictures will be even smaller by the browser maker thanks Mozjpeg 2.0 encoder. The open-source encoder is compatible with existing JPEG decoders, which may for example not be updated to load. The new, smaller jpegs browsers The improvement is mainly due to trellis quantization , an algorithm that is particularly suitable for the compression of images, and which is also used. include in Xvid and H.264

Facebook has already started the first tests of the new format. Moreover, the social network donated $ 60,000 to make. Developing Mozjpeg 3.0 may Last year asked Facebook Mozilla precisely to support webp, a relatively new format for images on Google. As yet there is no Mozilla obey given, though the reference is taken into consideration. In 2011, Mozilla said no plans for support to have.

From research that Mozilla has done himself would appear that jpeg in some cases more efficient than webp when looking at the number of bits required per pixel. The new standard high efficiency video coding, which is used in the successor to H.264, including in all cases the most efficient, but support for still images hevc compression is minimal.
