New users may want to skip to the Examples section at the end. To interlace all the GIFs in the current directory, you could say: gifsicle -batch -i *.gif With -batch, gifsicle will modify the files you specify instead of writing a new file to the standard output. To modify GIF files in place, use the -batch option. Use options like -delay, -loopcount, and -optimize to tune your animations. By default, it combines two or more input files into a “flipbook” animation: gifsicle pic1.gif pic2.gif pic3.gif > animation.gif Gifsicle is good at creating and manipulating GIF animations. The -i option, for example, tells gifsicle to interlace its inputs: gifsicle -i interlaced-pic.gif Gifsicle normally processes input GIF files according to its command line options and writes the result to the standard output. Gifsicle is a powerful command-line program for creating, editing, manipulating, and getting information about GIF images and animations. Modify all frames of a GIF using specific transformation options: gifsicle -b -crop 50, 50+ -50x -50 -scale 0.25 -flip-horizontal -rotate-90 path/to/input.gif.Delete the first 10 frames and all frames after frame 20 from a GIF: gifsicle -b path/to/input.gif -delete '# 0-9' '# 20-'.Reduce file size using lossy compression: gifsicle -b path/to/input.gif -optimize=3 -lossy= 100 -colors= 16 -dither.Make a GIF animation from selected GIFs: gifsicle *.gif -delay= 10 -loop > path/to/output.gif.Extract a frame from a GIF: gifsicle path/to/input.gif '# 0' > path/to/firstframe.gif.Unoptimize a GIF in place: gifsicle -b path/to/input.gif -unoptimize.Optimize a GIF as a new file: gifsicle path/to/input.gif -optimize=3 -o path/to/output.gif.Manipulates GIF images and animations Examples (TL DR)
