[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.

#### What is ImageMagick?
|
|
|
|
The 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.
|
|
|
|
ImageMagick utilizes multiple computational threads to increase performance and can read, process, or write mega-, giga-, or tera-pixel image sizes.
|
|
|
|
ImageMagick 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).
|
|
|
|
The 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.
|
|
|
|
ImageMagick is available from http://www.imagemagick.org/script/binary-releases.php. It runs on Linux, Windows, Mac Os X, iOS, Android OS, and others.
|
|
|

The authoritative ImageMagick web site is http://www.imagemagick.org. The authoritative source code repository is http://git.imagemagick.org/repos/ImageMagick/.

#### Features and Capabilities
|
|
|
|
Here are just a few examples of what ImageMagick can do:
|
|
|
|
* [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).
|
|
* [Transform](http://www.imagemagick.org/Usage/resize/): resize, rotate, deskew, crop, flip or trim an image.
|
|
* [Transparency](http://www.imagemagick.org/Usage/masking/): render portions of an image invisible.
|
|
* [Draw](http://www.imagemagick.org/Usage/draw/): add shapes or text to an image.
|
|
* [Decorate](http://www.imagemagick.org/Usage/crop/): add a border or frame to an image.
|
|
* [Special effects](http://www.imagemagick.org/Usage/blur/): blur, sharpen, threshold, or tint an image.
|
|
* [Animation](http://www.imagemagick.org/Usage/anim_basics/): create a GIF animation sequence from a group of images.
|
|
* [Text & comments](http://www.imagemagick.org/Usage/text/): insert descriptive or artistic text in an image.
|
|
* [Image gradients](http://www.imagemagick.org/script/gradient.php): create a gradual blend of one color whose shape is horizontal, vertical, circular, or ellipical.
|
|
* [Image identification](http://www.imagemagick.org/script/identify.php): describe the format and attributes of an image.
|
|
* [Composite](http://www.imagemagick.org/script/composite.php): overlap one image over another.
|
|
* [Montage](http://www.imagemagick.org/script/montage.php): juxtapose image thumbnails on an image canvas.
|
|
* [Generalized pixel distortion](http://www.imagemagick.org/Usage/distorts/): correct for, or induce image distortions including perspective.
|
|
* [Morphology of shapes](http://www.imagemagick.org/Usage/morphology/): extract features, describe shapes and recognize patterns in images.
|
|
* [Delineate image features](http://www.imagemagick.org/Usage/transform/#vision): Canny edge detection, mean-shift, Hough lines.
|
|
* [Motion picture support](http://www.imagemagick.org/script/motion-picture.php): read and write the common image formats used in digital film work.
|
|
* [Image calculator](http://www.imagemagick.org/script/fx.php): apply a mathematical expression to an image or image channels.
|
|
* [Connected component labeling](http://www.imagemagick.org/script/connected-components.php): uniquely label connected regions in an image.
|
|
* [Discrete Fourier transform](http://www.imagemagick.org/Usage/fourier/): implements the forward and inverse [DFT](http://en.wikipedia.org/wiki/Discrete_Fourier_transform).
|
|
* [Perceptual hash](http://www.fmwconcepts.com/misc_tests/perceptual_hash_test_results_510/index.html): maps visually identical images to the same or similar hash-- useful in image retrieval, authentication, indexing, or copy detection as well as digital watermarking.
|
|
* [Complex text layout](https://en.wikipedia.org/wiki/Complex_text_layout) bidirectional text support and shaping.
|
|
* [Color management](http://www.imagemagick.org/script/color-management.php): accurate color management with color profiles or in lieu of-- built-in gamma compression or expansion as demanded by the colorspace.
|
|
* [High dynamic-range images](http://www.imagemagick.org/script/high-dynamic-range.php): accurately represent the wide range of intensity levels found in real scenes ranging from the brightest direct sunlight to the deepest darkest shadows.
|
|

|
|
* [Virtual pixel support](http://www.imagemagick.org/script/architecture.php#virtual-pixels): convenient access to pixels outside the image region.
|
|
* [Large image support](http://www.imagemagick.org/script/architecture.php#tera-pixel): read, process, or write mega-, giga-, or tera-pixel image sizes.
|
|
* [Threads of execution support](http://www.imagemagick.org/script/architecture.php#threads): ImageMagick is thread safe and most internal algorithms are OpenMP-enabled to take advantage of speed-ups offered by multicore processor chips.
|
|
* [Distributed pixel cache](http://www.imagemagick.org/script/distribute-pixel-cache.php): offload intermediate pixel storage to one or more remote servers.
|
|
* [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.
|
|
* [ImageMagick on the iPhone](http://www.imagemagick.org/script/binary-releases.php#iOS): convert, edit, or compose images on your iPhone.

[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.

#### News
|
|
|
|
The 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.
