So you want to resize Gif animation?
Well, what's stopping you?
It is possible! And quite easy.
The application has a few built in restrictions.
Maximum image size (original and resized) is 600 in width and 600 in height.
Only .gif images are allowed.
Most animations will resize well although some aren't very high quality to begin with or may have been over optimised previously.
In that case, you'll see chopped frames, bad outline colors, or weird backgrounds.
You can preview your resized image on a number of background colors to check for excessive antialiasing, the white outline around a lot of small gifs, especially emoticons or clipart.
