ImageMagick is a program that can read, convert, and represent images in many formats because it contains many libraries.

ImageMagick allows you to crop images, add some effects, combine text and polygons, add rotation, and more. The program supports nearly 100 different image formats, from the most popular ones such as TIFF, JPG, PNG, GIF, BMP, PDF to the more specific ones.

ImageMagick also acts as an image converter. In addition, the application is completely free and will be distributed with the source code in case you want to change or improve your operations.
