The current release is ImageMagick 7.0.8-54. It runs on Linux, Windows, Mac Os X, iOS, Android OS, and others.

The authoritative ImageMagick web site is https://imagemagick.org. The authoritative source code repository is https://github.com/ImageMagick. We maintain a source code mirror at https://gitlab.com/ImageMagick. We continue to maintain the legacy release of ImageMagick, version 6, at https://legacy.imagemagick.org.

Features and Capabilities


Animation create a GIF animation sequence from a group of images.
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.
Decorate add a border or frame to an image.
Delineate image features Canny edge detection, Hough lines.
Discrete Fourier transform implements the forward and inverse DFT.
Draw add shapes or text to an image.
Histogram Equalization Use adaptive histogram equalization to improve contrast in images.
Image identification describe the format and attributes of an image.
Montage juxtapose image thumbnails on an image canvas.
Noise and color reduction Kuwahara Filter, mean-shift.
Text & comments insert descriptive or artistic text in an image.
Transparency render portions of an image invisible.
Virtual pixel support convenient access to pixels outside the image boundaries.





The ImageMagick development process ensures a stable API and ABI. Before each ImageMagick release, we perform a comprehensive security assessment that includes memory error, thread data race detection, and continuous fuzzing to help prevent security vulnerabilities.

As an analog to linear (RGB) and non-linear (sRGB) color colorspaces, as of ImageMagick 7.0.7-17, we introduce the LinearGray colorspace. Gray is non-linear grayscale and LinearGray is linear (e.g. -colorspace linear-gray).

Want more performance from ImageMagick? Try these options:

If these options are prohibitive, you can reduce the quality of the image results. The default build is Q16 HDRI. If you disable HDRI, you use half the memory and instead of predominately floating point operations, you use the typically more efficient integer operations. The tradeoff is reduced precision and you cannot process out of range pixel values (e.g. negative). If you build the Q8 non-HDRI version of ImageMagick, you again reduce the memory requirements in half-- and once again there is a tradeoff, even less precision and no out of range pixel values. For a Q8 non-HDRI build of ImageMagick, use these configure script options: --with-quantum-depth=8 --disable-hdri.
