ImageMagick is free, open source image processing software that’s been around for more than 25 years.
You may never have heard of it, or seen its logo, a
friendly-looking wizard with a binary-encrusted hat, a long white beard and an image-tweaking wand.
But there’s a good chance that you’ve used ImageMagick without even realising it, for example when you’ve uploaded images to a website or a blogging service for later use on web pages or in articles.
ImageMagick isn’t like GIMP, or Adobe Photoshop, or Apple’s Photo app, where you open up an image in a graphical window and then work on it interactively with a range of design tools from a menu.
ImageMagick is a set of command-line programs that’s ideal for the bulk processing of images in a repeatable way.
