USAGE

Usage: caesiumclt [OPTIONS] <--quality <QUALITY>|--lossless|--max-size <MAX_SIZE>> <--output <OUTPUT>|--same-folder-as-input> [FILES]...

Arguments:
  [FILES]...


Options:
  -q, --quality <QUALITY>
          sets output file quality between [0-100]

      --lossless
          perform lossless compression

      --max-size <MAX_SIZE>
          set the expected maximum output size in bytes

      --width <WIDTH>
          width of the output image, if height is not set will preserve aspect ratio

      --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

      --short-edge <SHORT_EDGE>
          sets the size of the shortest edge of the image

  -o, --output <OUTPUT>
          output folder

      --same-folder-as-input
          sets the output folder to be the same as the input folder, overwrites original files

      --format <FORMAT>
          convert to the selected output format, or keep the original

          [default: original]
          [possible values: jpeg, png, webp, tiff, original]

      --png-opt-level <PNG_OPT_LEVEL>
          select level for PNG optimization, between [0-6]

          [default: 3]

      --zopfli
          use zopfli when optimizing PNG files (it may take a very long time to complete)

  -e, --exif
          keeps EXIF info during compression

      --keep-dates
          keep original file date information

      --suffix <SUFFIX>
          add a suffix to the output filename

  -R, --recursive
          if input is a folder, scan subfolders too

  -S, --keep-structure
          keep the folder structure, can be used only with -R

  -d, --dry-run
          do not write output files

      --threads <THREADS>
          specify the number of parallel jobs (max is the number of processors available)

          [default: 1]

  -O, --overwrite <OVERWRITE>
          overwrite policy

          [default: all]

          Possible values:
          - all:    Always overwrite
