This software is a group of UNIX tools that use a Command Line Interface (CLI), does not have a "user-friendly" GUI. This is stated here for the convenience of those not familiar with UNIX and CLI, so they need not waste any bandwidth downloading this. Also, see 'Related Links', below, on this page.
ImageMagick is a robust collection of UNIX tools and libraries offered under a usage license to read, write, and manipulate an image in many image formats (over 89 major formats) including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick you can create images dynamically, making it suitable for Web applications. You can also resize, rotate, sharpen, color reduce, or add special effects to an image or image sequence and save your completed work in the same or differing image format. Image processing operations are available from the command line, or from the C, C++, Perl, Java, PHP, Python, or Ruby programming languages. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. ImageMagick's focus is on performance, minimizing bugs, and providing stable APIs and ABIs.
Here are just a few examples of what ImageMagick can do:
- Convert an image from one format to another (e.g. TIFF to JPEG)
- Resize, rotate, sharpen, color reduce, or add special effects to an image
- Create a montage of image thumbnails
- Create a transparent image suitable for use on the Web
- Turn a group of images into a GIF animation sequence
- Create a composite image by combining several separate images
- Draw shapes or text on an image
- Decorate an image with a border or frame
- Describe the format and characteristics of an image

RORO01 I WISH SOMEONE WOULD CREATE A GUI This software seems extremely useful but, unfortunately, many of us are not familiar with UNIX and Command Line Interface. (Version 6.4.5) | |

ImageMagick is an open source technology to create, edit, and compose bitmap images. It is used as a core for Pixelmator (Version 6.4.6) | |

MARK EVERITT Imagemagick is far too full featured for a single GUI! You could happily have multiple programs for various tasks and still not use it to its full potential. (Version 6.4.7) | |

WEBCHICK Not every program can be written to fulfill everyone's needs and skill sets. This is a venerable set of (mostly) command-line tools that will find the most use by developers, particularly those who work in a multi-platform environment. Its strengths lie primarily in the usefulness of these tools in scripts: whether it be processing one image on-the-fly or batch processing thousands of images. There are plenty of fine freeware GUI image processing applications out there, so if you're not looking for command-line image processing tools geared for developers, move along and no whining. (Version 6.4.8) | |

ANONYMOUS I still prefer SIPS from Mac OS X over ImageMagick. (Version 6.2.5) | |

TEKL Can sips sharpen images or it there another way like using Quartz filters? (Version 6.4.3) | |

JOHN NOWAK The simple reason we need ImageMagick is that other platforms rely on it heavily. Having it on OS X as well makes things easier for a lot of people, and helps improve compatability between platforms. (Version 6.2.3) | |

ANONYMOUS Command line tools are good. But I don't see why we need ImageMagick while Mac OS X Panther has SIPS. I am not a developer but I did write a short shell script with SIPS and it works fine. I still don't see what additional functionality ImageMagick brings to a Panther user. (Version 6.2.2) | |

ANONYMOUS read the documentation for sips, and read the documentation for imagemagick. imagemagick does many, many things that sips doesn't (Version 6.2.3) | |

ANONYMOUS ImageMagik is cross platform -- which is useful if you've already written something using it that you're moving to a Mac, or if there's a possibility of the software being moved to some other platform in the future. (Version 6.2.3) | |

This software package is meant for developers. You know, "Developers! Developers! Developers! Developers!" like the scary ape-man from Microsoft said. People who write software. I write a web-based app that allows its users to upload images, and thanks to ImageMagick, they can resize, crop, and scale the pictures without having to have a desktop program to do this. The techniques involved are very similar to something another guy came up with, that actually uses ImageMagick on its backend: http://codebehind.dk/scale_crop/ I write my program on my iMac, the same machine I also use Photoshop on. Isn't life grand? I, for one, am glad to know a new version of ImageMagick available, even though the only clicking involved is, um, firing up the terminal. And I say that as a 15+ year Mac user. (Version 6.2.2) | |

ANONYMOUS We don't need command line, we need clicks! Thats the way that MacOSX schould go! Command line is a step back in the Computer history! The best at this tool is that the tool is free. There are many other tools that works faster and are "easy to use" like Graphic converter, Batchfoto or Sizerox. I don't give this tool stars cause the developer has done his job. (Version 6.2.2) | |

ANONYMOUS What is the difference between ImageMagick and SIPS? I don't see any additional functionality in ImageMagick not available in SIPS... Or have I missed anything? (Version 6.2.2) | |

ANONYMOUS sounds great.... funny, i hear some of the users pooh poohing the idea of a gui... but there's a perl interface available from the site........ hmm......i was wondering...image magick + Perl...+ Cocoa? or does it matter when tiger comes? Now, if Seashore's toolset was a little better... or... Teal... or.. well, you know. Image Magick does look promising, though. (Version 6.2.0-6) | |

ANONYMOUS There is a .pkg version by Marc Liyanage that works great at http://www.entropy.ch/software/macosx/welcome.html#imagemagick (Version 6.2.0-5) | |
