ImageMagick is an open-source, free, and powerful application used for creating, editing, and converting images into various formats. Some of the images formats it supports include PNG, GIF, JPEG, PDF, EXR, WebP, and TIFF. Using ImageMagick, you can resize, rotate, crop, distort, flip, modify image colors, and apply a number of effects. You can also add text and different shapes to images.
