Use ImageMagick® to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (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.
The functionality of ImageMagick is typically utilized from the command-line or you can use the features from programs written in your favorite language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java), JuliaIO (Julia), L-Magick (Lisp), Lua (LuaJIT), NMagick (Neko/haXe), Magick.NET (.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 .
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.
The current release is ImageMagick . It runs on , , , , Android OS, and others.
The authoritative ImageMagick web site is . The authoritative source code repository is http://git.imagemagick.org/repos/ImageMagick. We maintain a source code mirror at GitLab and GitHub.
We continue to maintain the legacy release of ImageMagick, version 6, at .
Features and Capabilities
Here are just a few examples of what ImageMagick can do for you:
| create a GIF animation sequence from a group of images. | |
| Color management | accurate color management with color profiles or in lieu of-- built-in gamma compression or expansion as demanded by the colorspace. |
| Command-line processing | utilize ImageMagick from the command-line. |
| Complex text layout | bidirectional text support and shaping. |
| Composite | overlap one image over another. |
| Connected component labeling | uniquely label connected regions in an image. |
| add a border or frame to an image. | |
| , . | |
| implements the forward and inverse DFT. | |
| Distributed pixel cache | offload intermediate pixel storage to one or more remote servers. |
| add shapes or text to an image. | |
| Encipher or decipher an image | convert ordinary images into unintelligible gibberish and back again. |
| Format conversion | convert an image from one format to another (e.g. PNG to JPEG). |
| correct for, or induce image distortions including perspective. | |
| 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. |
| 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. |
| Image calculator | apply a mathematical expression to an image or image channels. |
| Image gradients | create a gradual blend of two colors whose shape is horizontal, vertical, circular, or elliptical. |
| Image identification | describe the format and attributes of an image. |
| ImageMagick on the iPhone | convert, edit, or compose images on your iOS device such as the iPhone or iPad. |
| Large image support | read, process, or write mega-, giga-, or tera-pixel image sizes. |
| Montage | juxtapose image thumbnails on an image canvas. |
| extract features, describe shapes, and recognize patterns in images. | |
| Motion picture support | read and write the common image formats used in digital film work. |
| , . | |
| Perceptual hash | map visually identical images to the same or similar hash-- useful in image retrieval, authentication, indexing, or copy detection as well as digital watermarking. |
| blur, sharpen, threshold, or tint an image. | |
| insert descriptive or artistic text in an image. | |
| Threads of execution support | ImageMagick is thread safe and most internal algorithms execute in parallel to take advantage of speed-ups offered by multicore processor chips. |
| resize, rotate, deskew, crop, flip or trim an image. | |
| render portions of an image invisible. | |
| Virtual pixel support | convenient access to pixels outside the image region. |
shows how to use ImageMagick from the command-line to accomplish any of these tasks and much more. Also, see Fred's ImageMagick Scripts: a plethora of command-line scripts that perform geometric transforms, blurs, sharpens, edging, noise removal, and color manipulations. With Magick.NET, use ImageMagick without having to install ImageMagick on your server or desktop.
