Okay, so whenever I make backgrounds, Twitter icons, videos though type of things it'll say for example "29KB" and whenever I make a Twitter icon sometimes it's file size is like 600KB and that takes FOREVER to upload. So is there any way I can make the file size smaller? Cuz it gets annoying when I make cool pictures or videos but then it's ruined because the file size is too big. So is it possible to maybe make the file size smaller?
