magick convert path/to/input_image.png -resize 50% path/to/output_image.png

• Scale an image keeping the original aspect ratio to a maximum dimension of 640x480:

magick convert path/to/input_image.png -resize 640x480 path/to/output_image.png

• Scale an image to have a specified file size:

magick convert path/to/input_image.png -define jpeg:extent=512kb path/to/output_image.jpg

• Vertically/horizontally append images:

magick convert path/to/image1.png path/to/image2.png … -append|+append path/to/output_image.png

• Create a GIF from a series of images with 100ms delay between them:

magick convert path/to/image1.png path/to/image2.png … -delay 10 path/to/animation.gif

magick convert -size 800x600 "xc:#ff0000" path/to/image.png
