How to Install ImageMagick 7 on Debian and Ubuntu
ImageMagick is a free and open source, feature-rich, text-based, and cross-platform image manipulation tool used to create, edit, compose or convert bitmap images. It runs on Linux, Windows, Mac Os X, iOS, Android OS, and many other operating systems.
It features command line processing, creation of animations, color management, special effects, text and comments, complex text layout, connected content labeling, image decoration, and drawing (add shapes or text to an image). It also supports format conversion, distributed pixel caching, large images, image transformation and so much more.
Although its functionality is typically utilized from the command line, you can use its features from programs written in any of the supported programming languages. It is designed for batch processing of images (i.e ImageMagick allows you to combine image processing operations in a script (shell, DOS, Python, Ruby, Perl, PHP, and many others)).
In this article, we will explain how to install and compile ImageMagick from source code in Debian and Ubuntu distributions.
Installing Dependencies for ImageMagick
To install ImageMagick from the source, you need a proper development environment with a compiler and related development tools. If you don’t have the required packages on your system, install build-essential as shown:
Once you’ve installed compilation dependencies, now you can download the ImageMagick source code.
Download ImageMagick Source Files
Go to the official ImageMagick download page and grab the latest “ImageMagick.tar.gz” source code package. Alternatively, you can use the following wget command to download the source code directly in the terminal as shown.
Once the download is complete, extract its content and move it into the extracted directory.
ImageMagick Compilation and Installation
Next, run the make command to perform the compilation.
Once the compilation is successful, install it and configure the dynamic linker run-time bindings as follows.
Finally, verify that ImageMagick 7 has been installed on your system by checking its version.

Install ImageMagick (Image Manipulation) Tool on RHEL/CentOS and Fedora
ImageMagick is a free open source simple software suite for any kind of image manipulation that is used for creating, editing, converting, displaying image files.
It can able to read and write over 200 image files such as JPEG, GIF, PNG, TIFF, and Photo CD image formats and it is also used for thumbnail or captcha generation. It also includes command-line options for creating transparent or animated gif image formats and many more features like resize, sharpen, rotate or add special effects to an image.
To use the ImageMagick tool with PHP or Perl programming language, you will need to install ImageMagick with the Imagick PHP extension for PHP and ImageMagick-Perl extension for Perl.
Imagick is a simple PHP extension for creating and modifying images using the ImageMagick API program. There is a confusion in name, as people think that ImageMagick and Imagick both are the same, but you can use ImageMagick without Imagick extension but you need both installed on your machine to use and run it.
Installing ImageMagick from Repository
First, install following prerequisite php-pear, php-devel and gcc packages to compile the Imagick PHP extension.
Install PHP Extensions in CentOS 8
Once you’ve installed php-pear, php-devel, and gcc packages, you may now install ImageMagick software for PHP and Perl support using yum command.
IMPORTANT: ImageMagick is not available in CentOS/RHEL 8, and it has been replaced with GraphicsMagick instead, which is a fork of ImageMagick.
To install GraphicsMagick on CentOS/RHEL 8, run the following command.
Install GraphicsMagick in CentOS 8
Next, verify that ImageMagick has been installed on your system by checking its version.
CentOS/RHEL 8 users, can run the following command to verify the version of GraphicsMagick installed on the system.
Installing ImageMagick 7 from Source Code
To install ImageMagick from source, you need a proper development environment with a compiler and related development tools. If you don’t have the required packages on your system, install development tools as shown:
Now, download the latest version of the ImageMagick source code using the following wget command and extract it.
Configure and compile the ImageMagick source code. Depending on your server hardware specs, this may take some time to finish.
Verify that the ImageMagick compile and install were successful.
Install Imagick PHP Extension
Next, compile the Imagick for PHP extension. To do, simply run the following ‘pecl‘ command. It will install ImageMagick and imagick PHP extension module ‘imagick.so‘ under /usr/lib/php/modules directory. If you are using a 64-bit system, the module directory path would be /usr/lib64/php/modules.
Note: It will ask you to provide Imagemagick installation prefix, simply hit enter to auto-detect.
Now, add the ‘imagick.so‘ extension to ‘/etc/php.ini‘ file.
Next, restart Apache webserver.
Verify the Imagick PHP extension by running the following command. You will see the Imagick extension similar to below.
Install GMagick PHP Extension
Run the following commands to compile and install GMagick PHP Extension.
Now, add the ‘gmagick.so‘ extension to ‘/etc/php.ini‘ file.
Next, restart the Apache webserver.
Verify gmagick PHP extension by running the following command.
Alternatively, you can create a file called ‘phpinfo.php‘ under website root directory (ex: /var/www/html/).
Add the following code.
Open your favorite web browser and type ‘http://localhost/phpinfo.php‘ or ‘http://ip-addresss/phpinfo.php‘ and verify the extension.

How to Install ImageMagick on Ubuntu 18.04 & 16.04 LTS
ImageMagick is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats like GIF, JPEG, PNG, Postscript, and TIFF. We can also 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.
This article will help you to install ImageMagick on 19.04, 18.04 & 16.04 LTS operating systems.
Step 1 – Prerequsities
First of all, You need to install the required packages in order to install ImageMagick and Imagick PHP extension. You can also visit our tutorial to install different versions of PHP on Ubuntu.
Step 2 – Install ImageMagick
After installing required packages, let’s install ImageMagick using the following command. ImageMagick package is available under default apt repositories.
Step 3 – Install imagick PHP Extension
At this point, you have successfully installed ImageMagick package on your system. Now, you need to install Imagick PHP extension, So that we can use it through PHP code.
For different PHP version’s you need to install the specific version of imagick like php7.1-imagick or php7.3-imagick etc.
Step 4 – Restart Apache and Verify
After completing above steps you need to reload apache service to enable php exension using following command
Now verify that module is enabled properly.
You can also create phpinfo() file to view ImageMagick on the web browser.

Install from Source
Chances are, ImageMagick is already installed on your computer if you are using some flavor of Linux, and its likely not installed if you are using some form of Windows. In either case, you can type the following to find out:
If the identify program executes and identifies itself as ImageMagick, you may not need to install ImageMagick from source unless you want to add support for additional image formats or upgrade to a newer version. You also have the option of installing a pre-compiled binary release. However, if you still want to install from source, choose a platform, Linux or Windows. Before installing from source, you may want to review recent changes to the ImageMagick distribution.
The authoritative source code repository is https://github.com/ImageMagick.
Install from Linux Source
ImageMagick builds on a variety of Linux and Linux-like operating systems including Linux, Solaris, FreeBSD, Mac OS X, and others. A compiler is required and fortunately almost all modern Linux systems have one. Clone the source repository:
Or download ImageMagick.tar.gz from imagemagick.org or a mirror and verify the distribution against its message digest.
Next configure and compile ImageMagick. Note the pkg-config script is required so that ImageMagick can find certain optional delegate libraries on your system. To configure, type:
If build fails, try gmake instead.
For advanced users, we recommend a modules build:
If ImageMagick configured and compiled without complaint, you are ready to install it on your system. Administrator privileges are required to install. To install, type
You may need to configure the dynamic linker run-time bindings:
Finally, verify the ImageMagick install worked properly, type
For a more comprehensive test, run the ImageMagick validation suite. Ghostscript and Freetype are prerequisites, otherwise expect the EPS, PS, PDF and text annotations tests to fail.
Congratulations, you have a working ImageMagick distribution and you are ready to use ImageMagick to convert, compose, or edit your images or perhaps you’ll want to use one of the Application Program Interfaces for C, C++, Perl, and others.
The above instructions will satisfy a great number of ImageMagick users, but we suspect a few will have additional questions or problems to consider. For example, what does one do if ImageMagick fails to configure or compile? Or what if you don’t have administrator privileges and what if you don’t want to install ImageMagick in the default /../usr/local folder? You will find the answer to these questions, and more, in Advanced Linux Source Installation.
Install from Windows Source
We recommend you first uninstall an existing ImageMagick, else you might be surprised that your magick/convert commands go to the old version.
Building ImageMagick source for Windows can be done with a modern version of Microsoft Visual Studio IDE. Users have reported success with the Borland C++ compiler as well. If you don’t have a compiler you can still install a self-installing binary release.
Clone the Github repo:
Unzip in a folder that does not need Admin permissions, otherwise Visual Studio will not be able to build the solution.
The configure.exe utility can also be run on the command line instead of through the GUI wizard. You can see an example in our GitHub actions build.
To verify ImageMagick is working properly, launch a MS-DOS Command Prompt window and type
You may want to add the full path to VisualMagick\bin for your environment PATH variable, so you can call Magick/convert from any directory.
For a more comprehensive test, run the ImageMagick validation suite:
Congratulations, you have a working ImageMagick distribution under Windows and you are ready to use ImageMagick to convert, compose, or edit your images or perhaps you’ll want to use one of the Application Program Interfaces for C, C++, Perl, and others.
The above instructions will satisfy a great number of ImageMagick users, but we suspect a few will have additional questions or problems to consider. For example, what does one do if ImageMagick fails to configure or compile? Or what if you want to install ImageMagick in a place other than the ImageMagick-7.1.0/VisualMagick/bin folder? You will find the answer to these questions, and more, in Advanced Windows Source Installation.

Advanced Linux Installation
It’s possible you don’t want to concern yourself with advanced installation under Linux or Linux systems. If so, you also have the option of installing a pre-compiled binary release or if you still want to install from source without all the fuss see the simple Install From Source instructions. However, if you want to customize the configuration and installation of ImageMagick under Linux or Linux systems, lets begin.
Download & Unpack
ImageMagick builds on a variety of Linux and Linux-like operating systems including Linux, Solaris, FreeBSD, Mac OS X, and others. A compiler is required and fortunately almost all modern Linux systems have one. Download ImageMagick.tar.gz from imagemagick.org or a mirror and verify the distribution against its message digest.
Unpack the distribution it with this command:
Now that you have the ImageMagick Linux/Linux source distribution unpacked, let’s configure it.
Configure
The configure script looks at your environment and decides what it can cobble together to get ImageMagick compiled and installed on your system. This includes finding a compiler, where your compiler header files are located (e.g. stdlib.h), and if any delegate libraries are available for ImageMagick to use (e.g. JPEG, PNG, TIFF, etc.). If you are willing to accept configure’s default options, and build from within the source directory, you can simply type:
Watch the configure script output to verify that it finds everything that you think it should. Pay particular attention to the last lines of the script output. For example, here is a recent report from our system:
You can influence choice of compiler, compilation flags, or libraries of the configure script by setting initial values for variables in the configure command line. These include, among others:
Here is an example of setting configure variables from the command line:
Any variable (e.g. CPPFLAGS or LDFLAGS) which requires a directory path must specify an absolute path rather than a relative path.
Here are the optional features you can configure:
| —enable-shared | build the shared libraries and support for loading coder and process modules. Shared libraries are preferred because they allow programs to share common code, making the individual programs much smaller. In addition shared libraries are required in order for PerlMagick to be dynamically loaded by an installed PERL (otherwise an additional PERL (PerlMagick) must be installed. |
By default the ImageMagick build is configured to formally install into a directory tree. This the most secure and reliable way to install ImageMagick. Use this option to configure ImageMagick so that it doesn’t use hard-coded paths and locates support files by computing an offset path from the executable (or from the location specified by the MAGICK_HOME environment variable. The uninstalled configuration is ideal for binary distributions which are expected to extract and run in any location.
Certain ImageMagick algorithms, for example convolution, can achieve a significant speed-up with the assistance of the OpenMP API when running on modern dual and quad-core processors.
Here are the optional packages you can configure:
| —with-quantum-depth | number of bits in a pixel quantum (default 16). |
The number of bits in a quantum determines how many values it may contain. Each quantum level supports 256 times as many values as the previous level. The following table shows the range available for various quantum sizes.
Larger pixel quantums can cause ImageMagick to run more slowly and to require more memory. For example, using sixteen-bit pixel quantums can cause ImageMagick to run 15% to 50% slower (and take twice as much memory) than when it is built to support eight-bit pixel quantums.
Specify a different image pixel cache threshold with this option. This sets the maximum amount of heap memory that ImageMagick is allowed to consume before switching to using memory-mapped temporary files to store raw pixel data.
Normally, external program names are substituted into the delegates.xml configuration file without full paths. Specify this option to enable saving full paths to programs using locations determined by configure. This useful for environments where programs are stored under multiple paths, and users may use different PATH settings than the person who builds ImageMagick.
The PerlMagick module is normally installed using the Perl interpreter’s installation PREFIX, rather than ImageMagick’s. If ImageMagick’s installation prefix is not the same as PERL’s PREFIX, then you may find that PerlMagick’s sudo make install step tries to install into a directory tree that you don’t have write permissions to. This common when PERL is delivered with the operating system or on Internet Service Provider (ISP) web servers. If you want PerlMagick to install elsewhere, then provide a PREFIX option to PERL’s configuration step via «—with-perl-options=PREFIX=/some/place». Other options accepted by MakeMaker are ‘LIB’, ‘LIBPERL_A’, ‘LINKTYPE’, and ‘OPTIMIZE’. See the ExtUtils::MakeMaker(3) manual page for more information on configuring PERL extensions.
Specify the directory containing MS-Windows-compatible fonts. This not necessary when ImageMagick is running under MS-Windows.
ImageMagick is now configured and ready to build
Build
Once ImageMagick is configured, these standard build targets are available from the generated make files:
In most cases you will simply want to compile ImageMagick with this command:
Once built, you can optionally install ImageMagick on your system as discussed below.
Install
Now that ImageMagick is configured and built, type:
To confirm your installation of the ImageMagick distribution was successful, ensure that the installation directory is in your executable search path and type:
The ImageMagick logo is displayed on your X11 display.
To verify the ImageMagick build configuration, type:
For a more comprehensive test, you run the ImageMagick test suite by typing:
Ghostscript is a prerequisite, otherwise the EPS, PS, and PDF tests will fail. Note that due to differences between the developer’s environment and your own it is possible that a few tests may fail even though the results are ok. Differences between the developer’s environment and your own may include the compiler, the CPU type, and the library versions used. The ImageMagick developers use the current release of all dependent libraries.
Linux-specific Build instructions
Download ImageMagick.src.rpm from imagemagick.org or its mirrors and verify the distribution against its message digest.
Build ImageMagick with this command:
After the build you, locate the RPMS folder and install the ImageMagick binary RPM distribution:
Mac OS X-specific Build instructions
Perform these steps as an administrator or with the sudo command:
Install MacPorts. Download and install MacPorts and type the following commands:
This installs many of the delegate libraries ImageMagick will utilize such as JPEG and FreeType.
Install the latest Xcode from Apple.
Use the port command to install any delegate libraries you require, for example:
Now lets build ImageMagick:
Download the ImageMagick source distribution and verify the distribution against its message digest.
Unpack and change into the top-level ImageMagick directory:
To verify your install, type
to list all the fonts ImageMagick knows about.
To test the ImageMagick GUI, in a new shell, type:
MinGW-specific Build instructions
Although you can download and install delegate libraries yourself, many are already available in the GnuWin32 distribution. Download and install whichever delegate libraries you require such as JPEG, PNG, TIFF, etc. Make sure you specify the development headers when you install a package. Next type,
Dealing with Unexpected Problems
Chances are the download, configure, build, and install of ImageMagick went flawlessly as it is intended, however, certain systems and environments may cause one or more steps to fail. We discuss a few problems we’ve run across and how to take corrective action to ensure you have a working release of ImageMagick
Build Problems
Some systems may fail to link at build time due to unresolved symbols. Try adding the LDFLAGS to the configure command line:
Dynamic Linker Run-time Bindings
Solaris and Linux systems have the ldd command which is useful to track which libraries ImageMagick depends on:
Delegate Libraries
On occasion you may receive these warnings:
This exception indicates that an external delegate library or its headers were not available when ImageMagick was built. To add support for the image format, download and install the requisite delegate library and its header files and reconfigure, rebuild, and reinstall ImageMagick. As an example, lets add support for the JPEG image format. First we install the JPEG RPMS:
Now reconfigure, rebuild, and reinstall ImageMagick. To verify JPEG is now properly supported within ImageMagick, use this command:
You should see a mode of rw- associated with the JPEG tag. This mode means the image can be read or written and can only support one image per image file.
