Command-line options

Example: converting all .png files to .jpg format in a directory.
magick mogrify -format jpg -path /some/output_dir/ -sampling-factor 4:2:0 -quality 100 -interlace plane -strip *.png

Notes

• If the -path option is used with mogrify, the original (input) files won't be overwritten. New output files will be written to the path.
• -interlace option: use either 'Line' or 'Plane' to create an interlaced PNG or progressive JPEG.
  Reduces JPEG file sizes by a small margin.
• quality level significantly affects file size for higher resolutions. For JPEG, try a value of 85 or lower for images with high image resolutions in order to achieve small(er) file sizes.
