Optimize gif using command line [linux gifsicle tool]

Run the following command in your directory where image is located.

Command:

gifsicle -i anim.gif -O3 --colors 256 -o anim-opt.gif
 

my gif got reduced from 15.2 to 12.5 mb you can further reduce it by setting --colors 8 instead of 32.


And finally I reduced it to a size 252K which OfCourse not look that much cute but ok I need it for a purpose.
This will optimize and reduce to 256 colors, if the animation uses more colors 
(the example image does).

You can reduce the size by reducing the number of colors:

1.512KB, 256 colors

2.412KB, 128 colors

3.340KB, 64 colors

4. 240, 32 colors

5.140, 16 colors
