The mogrify command recognizes these options. You can find additional examples of using mogrify in Examples of ImageMagick Usage. They are copies of their respective PNG images except are stored in the JPEG image format.

Here image files 1.png, 2.png, etc., are left untouched and files 1.jpg, 2.jpg, etc., are created. You can resize all your JPEG images in a folder to a maximum dimension of 256x256 with this command: magick mogrify -resize 256x256 *.jpgįinally, we convert all our PNG images in a folder to the JPEG format: magick mogrify -format jpg *.png Rose: magick mogrify -resize 50% rose.jpg To get started, let's reduce the size of our We list a few examples of the mogrify command here to illustrate its usefulness and ease of use.

See Command Line Processing for advice on how to structure your mogrify command or see below for sample usages of the command. This tool is similar to magick except that the original image file is overwritten (unless you change the file suffix with the -format option) with any changes you request. Use the magick mogrify program to resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more.
