ImageMagick – create, edit, compose, or convert bitmap images

Last Updated on July 11, 2023

ImageMagick is an open source software suite to create, edit, and compose bitmap images. All manipulations can be achieved through shell commands as well as through a graphical interface.

The software can read, convert and write images in a huge variety of formats (over 200) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF.

Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and B├ęzier curves.

Features include:

  • Format conversion: convert an image from one format to another (e.g. PNG to JPEG).
  • Transform: resize, rotate, crop, flip or trim an image.
  • Transparency: render portions of an image invisible.
  • Draw: add shapes or text to an image.
  • Decorate: add a border or frame to an image.
  • Special effects: blur, sharpen, threshold, or tint an image.
  • Animation: create a GIF animation sequence from a group of images.
  • Text & comments: insert descriptive or artistic text in an image.
  • Image identification: describe the format and properties of an image.
  • Composite: overlap one image over another.
  • Montage: juxtapose image thumbnails on an image canvas.
  • Motion picture support: read and write the common image formats used in digital film work.
  • Image calculator: apply a mathematical expression to an image or image channels.
  • High dynamic-range images: accurately represent the wide range of intensity levels found in real scenes ranging from the brightest direct sunlight to the deepest darkest shadows.
  • Large image support: read, process, or write mega- and giga-pixel image sizes.
  • Encipher or decipher an image: convert ordinary images into unintelligible gibberish and back again.
  • Threads of execution support: ImageMagick is thread safe and many internal algorithms are already threaded to take advantage of speed-ups offered by the dual and quad-core processor technologies.
  • Take screenshots using the import command.
