New Mozilla Encoder Improves JPEG Compression

jlp2097 writes "As reported by Heise, Mozilla has introduced a new JPEG encoder (German [Google-translated to English]) called mozjpeg. Mozjpeg promises to be a 'production-quality JPEG encoder that improves compression while maintaining compatibility with the vast majority of deployed decoders.' The Mozilla Research blog states that Mozjpeg is based on libjpeg-turbo with functionality added from jpgcrush. They claim an average of 2-6% of additional compression for files encoded with libjpeg and 10% additional compression for a sample of 1500 jpegs from Wikipedia — while maintaining the same image quality."

    Wikipedia might care.

    If 2-6% is nothing, why not donate that percentage of your monthly salary to a good cause?

    The file may be slightly bigger, but who cares.

    Anyone with a metered internet connection. Which is a depressingly large set of people, and signs are that it's going to get larger.

    PNG is great for everything but actual photos, and should be used for just that: everything but photos. But photos really do need the extra boost from lossy compression.

    Seems like a negligible improvement..

    Yes WebP would be a better choice

    It's a shame JPEG2000 debuted dead on arrival thanks to patent encumbrances. Creation of a superior open lossy image compression standard seems to have been left behind in favor of video. We have PNG and Theora, but nothing free that improves on jpeg.

    Because I remember watching graphics load line by line and that sucked.
