Resizing images from the CLI
An easy way to resize images quickly from the command line on your Mac. Navigate to the directory where the images you wish to resize are, using cd. I use a wildcard search (*) to resize all images in a directory, but to resize individual images, just swap *.JPG with the image’s filename. Here, I’m setting the maximum dimension (width or height, depending on whether the image is landscape or portrait) to 1920, or 1080p. sips -Z 1920 *.JPG
