Create, edit, manipulate, and get information about GIF files. More information: https://www.lcdf.org/gifsicle.
- 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}}
