I've been buying Corel PaintShop to edit GIFs because it can do two things:
- Count the number of colours in a GIF
- Reduce the size of the colour palette
So, for example, lets say I count the number of colours in a GIF and find out the image only contains eight colours. I can then decrease the colour depth from 256 to 8, which reduces the size of the file.
Is there a free program that can do this?
