ImageMagick - is a free software suite for the creation, modification and
display of bitmap images.
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, GIF, HEIC, 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 B\['e]zier 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), magick (R), 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 a derived 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, thread data race detection, and continuous fuzzing to
help prevent security vulnerabilities.
The current release is ImageMagick 7.0.8-11. 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

ImageMagick includes a number of command-line utilities for manipulating images.
Most of you are probably accustom to editing images one at a time with a
graphical user interface (GUI) with such programs as gimp or Photoshop.
However, a GUI is not always convenient. Suppose you want to process an image
dynamically from a web script or you want to apply the same operations to many
images or repeat a specific operation at different times to the same or
different image. For these types of operations, the command-line image
processing utility is appropriate.
In the paragraphs below, find a short description for each command-line tool.Cl
ick on the program name to get details on the program usage and a list of
comman d-line options that alters how the program performs. If you are just
getting acq uainted with ImageMagick, start at the top of the list, the
convert program, and
work your way down. Also be sure to peruse Anthony Thyssen's tutorial on how to
use ImageMagick utilities to convert, compose, or edit images from the command-
Read images into memory, and perform operations on those images, and write
then out to either the same of some other image file format.
The "-script" option can be switch from processing command line
options, to reading options from a file or pipeline.
As "magick" command but with an implied "-script"
option. Allows it to be used in special "#!/usr/bin/env
magick-script" scripts that will search for the
"magick-script" command anywhere along the users command path,
rather than in a hardcorded command location.
Backwards compatiblity for ImageMagick version 6 "convert".
Essentually an alias to a restrictive form of the "magick"
command, which should be used instead.
resize an image, blur, crop, despeckle, dither, draw on, flip, join,
re-sample, and much more. Mogrify overwrites the original image file,
whereas, convert writes to a different image file.
describes the format and characteristics of one or more image files.
overlaps one image over another.
create a composite image by combining several separate images. The images
are tiled on the composite image optionally adorned with a border, frame,
image name, and more.
mathematically and visually annotate the difference between an image and its
is a lightweight tool to stream one or more pixel components of the image or
portion of the image to your choice of storage formats. It writes the
pixel components as they are read from the input image a row at a time
making stream desirable when working with large images or when you require
raw pixel components.
displays an image or image sequence on any X server.
animates an image sequence on any X server.
saves any visible window on an X server and outputs it as an image file. You
can capture a single window, the entire screen, or any rectangular portion
of the screen.
interprets and executes scripts written in the Magick Scripting Language
