ImageMagick, invoked from the command line as magick, is a free and open-source[3] cross-platform software suite for displaying, creating, converting, modifying, and editing raster images.

It was freely released in 1990 when DuPont agreed to transfer copyright to ImageMagick Studio LLC, still currently the project maintainer organization.

[5][6][7] In May 2016, it was reported that ImageMagick had a vulnerability through which an attacker can execute arbitrary code on servers that use the application to edit user-uploaded images.

[9] The security flaw was due to ImageMagick calling backend tools without first properly checking to ensure path and file names are free of improper shell commands.

A number of programs, such as Drupal, MediaWiki, phpBB, and vBulletin, can use ImageMagick to create image thumbnails if installed.

One of the basic and thoroughly-implemented features of ImageMagick is its ability to efficiently and accurately convert images between different file formats (it uses the command magick to achieve this).
