In this tutorial, we will show you how to install ImageMagick on AlmaLinux 8. For those of you who didn’t know, ImageMagick is an open-source software suite for creating, editing, converting, and modifying bitmap images. With ImageMagick, you can read and write over 200 image formats, including DPX, EXR, GIF, JPEG, PDF, PNG, and many more. ImageMagick is also available across all major platforms, including Android, BSD, Linux, Windows, Mac OSX, iOS, and many others.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the ImageMagick on an AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.
Prerequisites
- A server running one of the following operating systems: AlmaLinux 8, CentOS, or Rocky Linux 8.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- A
non-root sudo useror access to theroot user. We recommend acting as anon-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Step 3. ImageMagick Terminal Commands.
Table of commands and tools that can be used with ImageMagick:
| Command | Description |
|---|---|
| animate | Display an image sequence as an animation. |
| compare | Analyze two images, and visualize mathematical differences between them. |
| composite | Compose one image over another with variable transparency to create a composite image. |
| conjure | Interpret and execute scripts written in MSL, the Magick Scripting Language. |
| convert | Convert images from one file format to another. This tool can also blur, crop, despeckle, dither, and otherwise modify the content of an image. |
| display | A simple image viewer. |
| identify | Display the image dimensions, quality, and other image metadata. |
| import | Capture the screen to an image file. |
| mogrify | Modify an image. Similar to converting, but overwrites the original image. |
| montage | Create an image composed of smaller images. This command can create a single image containing thumbnails of many images. |
| stream | Process image data and store it in a file as it is being streamed from an input source. Useful for situations with slow data streams or huge images whose data processing should begin before the entire image is stored. |
For example, use the convert logo command as follows:
convert logo: logo.gif
