Working on animated gif

I'm working with a page that use animated gif and I want to know how to do that gif has the automatic background so it does not differ from the bottom of the page?

Put the background transparent, thus no matter what the color of the background, you will always see that on the page.

If I have to be set background transparent but dont know how or where can I do this. Thanks for your help.
