description         optimizer for PNG files

long_description    pngcrush reads in a PNG image, and writes it out again, \
                    with the optimum filter_type and zlib_level. It uses \
                    brute force (trying filter_type none, and libpng adaptive \
                    filtering, with compression levels 3 and 9). It does the \
                    most time-consuming method last in case it turns out to \
                    be the best. Optionally, it can remove unwanted chunks or \
                    add gAMA and sRGB chunks.
