About Gifsicle
Gifsicle is a command-line tool for creating, editing and inspecting GIF images and animations. It can assemble an animation from multiple GIF files with a set delay and looping, extract, replace, delete or insert individual frames, control interlacing, comments, looping and transparency, optimize animations by storing only the changed portion of each frame, and shrink colormaps or switch images to the Web-safe palette. A batch mode changes GIF files in place, and the tool prints detailed information about a GIF, including comments. Two companion programs are bundled: gifview, a lightweight animated-GIF viewer that can show slideshows or play in real time, and gifdiff, which compares two GIFs for identical visual appearance. Source code and a man page are provided, and prebuilt binaries are listed for Debian, FreeBSD, NetBSD, macOS (Homebrew, MacPorts), DOS and Windows; the MacPorts package may be out of date. Building from source requires an ANSI C compiler and the software is described as freely available. Pricing is not stated beyond that.
