About ImageMagick
ImageMagick is the standard way to process images from a script. Resize a thousand photos, convert a directory of TIFFs to JPEG, composite a watermark, generate thumbnails, read a PDF page as an image: all of it is one command, and it handles over 200 formats.
It is written in C, runs on Linux, Windows and macOS, and provides APIs for most programming languages as well as the command line, which is why it sits inside a great deal of web and scientific software rather than being used directly.
One important note the project makes itself: you should create a security policy suited to your environment before using it, particularly if it will process files from untrusted sources, and verify that policy with their validation tool. ImageMagick's format handling has been a source of vulnerabilities in the past.
Strengths
- Over 200 formats, with conversion, resizing, compositing and effects from one command
- APIs for most programming languages as well as the command line
- Runs everywhere and is packaged by every distribution
- The de facto standard, so answers to almost any task already exist
Limitations
- The project advises creating and validating a security policy before use, especially with untrusted files
- Its format handling has been a repeated source of security vulnerabilities
- The command syntax is famously order-sensitive and hard to remember
- Version 6 and version 7 have different command names, which confuses copied examples
