ImageMagick is a free program suite to create, edit, and compose bitmap images. It can read, convert and write images in a large variety of formats. Images can be cropped, colors can be changed, various effects can be applied, images can be rotated and combined, and text, lines, polygons, ellipses and curves can be added to images and stretched and rotated.

ImageMagick is free software: it is delivered with full source code and can be freely used, copied, modified and distributed. Its license is compatible with the GPL. It runs on all major operating systems.

ImageMagick supports many image formats (over 90) including formats like GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX.

Features and Capabilities
Here are just a few examples of what ImageMagick can do:
1. Format conversion: convert an image from one format to another (e.g. PNG to JPEG).
2. Transform: resize, rotate, crop, flip or trim an image.
3. Transparency: render portions of an image invisible.
4. Draw: add shapes or text to an image.
5. Decorate: add a border or frame to an image.
6. Special effects: blur, sharpen, threshold, or tint an image.
7. Animation: create a GIF animation sequence from a group of images.
8. Text & comments: insert descriptive or artistic text in an image.
9. Image identification: describe the format and attributes of an image.
10. Composite: overlap one image over another.
11. Montage: juxtapose image thumbnails on an image canvas.
12. Generalized pixel distortion: correct for, or induce image distortions including perspective.
13. Morphology of shapes: extract features, describe shapes and recognize patterns in images.
14. Motion picture support: read and write the common image formats used in digital film work.
15. Image calculator: apply a mathematical expression to an image or image channels.
16. Discrete Fourier transform: implements the forward and inverse DFT.
17. High dynamic-range images: accurately represent the wide range of intensity levels found in real scenes ranging from the brightest direct sunlight to the deepest darkest shadows.
18. Encipher or decipher an image: convert ordinary images into unintelligible gibberish and back again.
19. Virtual pixel support: handy access to pixels outside the image region.
20. Large image support: read, process, or write mega-, giga-, or tera-pixel image sizes.
21. Threads of execution support: ImageMagick is thread safe and most internal algorithms are OpenMP-enabled to take advantage of speed-ups offered by multicore processor chips.
22. Heterogeneous distributed processing: certain algorithms are OpenCL-enabled to take advantage of speed-ups offered by executing in concert across heterogeneous platforms consisting of CPUs, GPUs, and other processors.
23. ImageMagick on the iPhone: convert, edit, or compose images on your iPhone.

Most of the functionality of ImageMagick can be used interactively from the command line; more often, however, the features are used from programs written in the programming languages C, Ch, C++, Java, Perl, PHP, Python, Ruby, Tcl/Tk, for which ready-made ImageMagick interfaces (PerlMagick, Magick++, PythonMagick, MagickWand for PHP, RMagick, TclMagick, and JMagick) are available. This makes it possible to modify or create images automatically and dynamically.
