- Optimize a GIF as a new file:
gifsicle
path/to/input.gif --optimize=3 -o
path/to/output.gif
- Use [b]atch mode (modify each given file in place) and unoptimize a GIF:
gifsicle -b
path/to/input.gif --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 --delay=
10 --loop >
path/to/output.gif
- Reduce file size using lossy compression:
gifsicle -b
path/to/input.gif --optimize=3 --lossy=
100 --colors=
16 --dither
- Delete the first 10 frames and all frames after frame 20 from a GIF:
gifsicle -b
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 --crop
starting_x,
starting_y+
rect_widthx
rect_height --scale
0.25 --flip-horizontal --rotate-
90|180|270
