    JPEG Lossy

    I spent some time studying the optimization of JPEG with losses.
    There was a following idea is based on a Progressive jpeg. We need: mozjpeg and jsk.
    Take this image and optimise using mozjpeg.

    480 790 bytes.

    Jsk skip through, you will have 16 new images different kachestva.
    For example scan_010 - 222 874 bytes

    Optimization mozjpeg is based on the technology -scans file . The idea arose to adjust the value of the parameter scans?

    For comparison jpegmini - 178 695 bytes.
