Your best option is GIMP. Put a layer at the back of your image and fill
it with the desired background colour that the gif will sit on. eg white
if the gif will be on a white background
Flatten your image and convert it to indexed format. Then add an alpha
chanel again.
Then select the background region with the contiguous selection tool
without a tolerance. Clear you selection and save as a gif.
This is as good as you can get with gif. It will look good on one
background colour - but that is it. gif is a useless format. You just
have to live with it.
