How to batch resize gif files without loosing to much definition.

Sometimes resizing distorts the images even when decreasing the size, pixels or percentage, the results are the same.

The best way to do this especially in batch mode is by using Fast Stone. Settings to use are as follows:

Use the advanced options for resizing, then on the first tab window, select "nearest" in the drop down next to the "filter" option on the left, important NOT to click on "use fastest filter" that is the one that distorts the files.
