Nope you guys are right. There's really not a more simple way to do it. you either pull it apart pic by pic and shrink each one or you delete frames (pics) altogether.
There are some apps that can do it with just a click, but they are higher end animations apps. My best suggestion would be to see if there are multiple pics of the same frame. If so delete all the multiples.
