 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.
