A professional-grade program like Adobe Flash allows users to make completely original animated cartoons but requires a fair amount of skill and time to learn the program. Meanwhile, websites such as GoAnimate allow users to make a cartoon with premade characters and settings.
There are many programs and websites that allow users to make their own cartoons. The choice of which to use depends on skill level, desired style and how much customization the user would like to do. While Adobe Flash is the industry standard, programs such as Toon Boom and Anime Studio are targeted at hobbyists who want to learn how to make cartoons.
