Optimize a GIF as a new file:

gifsicle {{path/to/input.gif}} {{[-O|--optimize=]}}3 {{[-o|--output]}} {{path/to/output.gif}}

Use batch mode (modify each given file in place) and unoptimize a GIF:

gifsicle {{[-b|--batch]}} {{path/to/input.gif}} {{[-U|--unoptimize]}}

Extract a frame from a GIF:

gifsicle {{path/to/input.gif}} '#{{0}}' > {{path/to/first_frame.gif}}

Make a GIF animation from selected GIFs:

gifsicle {{*.gif}} {{[-d|--delay]}} {{10}} {{[-l|--loop]}} > {{path/to/output.gif}}

Reduce file size using lossy compression:

gifsicle {{[-b|--batch]}} {{path/to/input.gif}} {{[-O|--optimize=]}}3 --lossy={{100}} {{[-k|--colors]}} {{16}} {{[-f|--dither]}}

Delete the first 10 frames and all frames after frame 20 from a GIF:

gifsicle {{[-b|--batch]}} {{path/to/input.gif}} --delete '#{{0-9}}' '#{{20-}}'

Modify all frames by cropping them to a rectangle, changing their scale, flipping them, and rotating them:

gifsicle {{[-b|--batch]}} --crop {{starting_x}},{{starting_y}}+{{rect_width}}x{{rect_height}} --scale {{0.25}} --flip-horizontal --rotate-{{90|180|270}} {{path/to/input.gif}}
