Gifsicle for Windows is a fork of the program Gifsicle made to build easily on Windows. Gifsicle manipulates GIF image files. Depending on command line options, it can merge several GIFs into a GIF animation; explode an animation into its component frames; change individual frames in an animation; turn interlacing on and off; add transparency; add delays, disposals, and looping to animations; add and remove comments; flip and rotate; optimize animations for space; change images' colormaps; and other things.

The Gifsicle package comes with NO WARRANTY, express or implied, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose.

Nightly binaries are available on the releases page. You may also download the source code for a release from that page in a .zip or .tar.gz file. The source code is also available to be downloaded via the Git repository.

To build Gifsicle for Windows, simply open the solution file in Visual Studio 2013.2 CTP (or newer) and build the solution! You will find the file Gifsicle.exe in the Release directory.

Please email Eddie Kohler if you have trouble building or running Gifsicle, or if you have suggestions or patches. If you are having trouble with Windows-specific functionality, you can contact me with an issue on GitHub!
