    caesiumcl [FLAGS] [OPTIONS] --max-size <max-size> --output <output> --quality <quality> [FILE]...

FLAGS:
    -d, --dry-run           do not compress files but just show output paths
    -e, --exif              keeps EXIF info during compression
    -h, --help              Prints help information
        --keep-dates        keep original file date information
    -S, --keep-structure    keep the folder structure, can be used only with -R
    -Q, --quiet             suppress all output

    -V, --version           Prints version information
        --zopfli            use zopfli when optimizing PNG files (it may take a very long time to complete)

OPTIONS:
        --height <height>                  height of the output image, if width is not set will preserve aspect ratio
        --long-edge <long-edge>            sets the size of the longest edge of the image
        --max-size <max-size>              set the expected maximum output size in bytes
    -o, --output <output>                  output folder
        --output-format <output-format>    convert the image to the selected format (jpg, png, webp, tiff) [default:

    -q, --quality <quality>                sets output file quality between [0-100], 0 for optimization
        --short-edge <short-edge>          sets the size of the shortest edge of the image
        --threads <threads>                specify the number of parallel jobs (max is the number of processors
                                           available) [default: 0]
        --verbose <verbose>                select how much output you want to see, 0 is equal to -Q, --quiet [default:
                                           1]
        --width <width>                    width of the output image, if height is not set will preserve aspect ratio
