gifsicle 1.93 Edit GIF images and animations

Gifsicle is a command-line GIF image manipulation tool that:

  • Provides a batch mode for changing GIFs in place.

  • Prints detailed information about GIFs, including comments.

  • Control over interlacing, comments, looping, transparency, etc.

  • Creates well-behaved GIFs: removes redundant colors, only uses local color tables, etc.

  • Shrinks colormaps and change images to use the Web-safe palette.

  • Optimizes GIF animations, or unoptimizes them for easier editing.

Two other programs are included with Gifsicle: gifview is a lightweight animated-GIF viewer, and gifdiff compares two GIFs for identical visual appearance.
