7[ImageMagick®](http://www.imagemagick.org/) is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of [formats](http://www.imagemagick.org/script/formats.php) (over 200) including PNG, JPEG, JPEG-2000, GIF, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

15#### What is ImageMagick?
16
17The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java), L-Magick (Lisp), NMagick (Neko/haXe), MagickNet (.NET), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface, use ImageMagick to modify or create images dynamically and automagically.
18
19ImageMagick utilizes multiple computational threads to increase performance and can read, process, or write mega-, giga-, or tera-pixel image sizes.
20
21ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may use, copy, modify, and distribute in both open and proprietary applications. It is distributed under the Apache 2.0 [license](http://www.imagemagick.org/script/license.php).
22
23The ImageMagick development process ensures a stable API and ABI. Before each ImageMagick release, we perform a comprehensive security assessment that includes memory error and thread data race detection to prevent security vulnerabilities.
24
25ImageMagick is available from http://www.imagemagick.org/script/binary-releases.php. It runs on Linux, Windows, Mac Os X, iOS, Android OS, and others.

29#### Features and Capabilities
30
31Here are just a few examples of what ImageMagick can do:
32
33* [Format conversion](http://www.imagemagick.org/script/convert.php): convert an image from one [format](http://www.imagemagick.org/script/formats.php) to another (e.g. PNG to JPEG).
34* [Transform](http://www.imagemagick.org/Usage/resize/): resize, rotate, deskew, crop, flip or trim an image.
35* [Transparency](http://www.imagemagick.org/Usage/masking/): render portions of an image invisible.
36* [Draw](http://www.imagemagick.org/Usage/draw/): add shapes or text to an image.
37* [Decorate](http://www.imagemagick.org/Usage/crop/): add a border or frame to an image.
38* [Special effects](http://www.imagemagick.org/Usage/blur/): blur, sharpen, threshold, or tint an image.
39* [Animation](http://www.imagemagick.org/Usage/anim_basics/): create a GIF animation sequence from a group of images.
40* [Text & comments](http://www.imagemagick.org/Usage/text/): insert descriptive or artistic text in an image.
41* [Image gradients](http://www.imagemagick.org/script/gradient.php): create a gradual blend of one color whose shape is horizontal, vertical, circular, or ellipical.

61* [Heterogeneous distributed processing](http://www.imagemagick.org/script/architecture.php#distributed): 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.
62* [ImageMagick on the iPhone](http://www.imagemagick.org/script/binary-releases.php#iOS): convert, edit, or compose images on your iPhone.

64[Examples of ImageMagick Usage](http://www.imagemagick.org/Usage/), shows how to use ImageMagick from the command-line to accomplish any of these tasks and much more. Also, see [Fred's ImageMagick Scripts](http://www.fmwconcepts.com/imagemagick/): a plethora of command-line scripts that perform geometric transforms, blurs, sharpens, edging, noise removal, and color manipulations. With [Magick.NET](https://magick.codeplex.com/), use ImageMagick without having to install ImageMagick on your server or desktop.

66#### News
67
68The design of ImageMagick is an evolutionary process, with the design and implementation efforts serving to influence and guide further progress in the other. With [ImageMagick version 7](http://nextgen.imagemagick.org), we aim to improve the design based on lessons learned from the version 6 implementation. See the [porting](http://www.imagemagick.org/script/porting.php) guide to track the progress of the version 7 development effort.
