For the same reason that our atmosphere on Earth does not escape into space - gravity.
Where a planet or moon has an atmosphere, it is the gravity of the moon or planet that holds the atmosphere on the planet or moon.
gravity keeps the giants planet's gasas from escaping
because the gravity keeps the giants planets' gases from escaping.
because the gravity keeps the giants planets' gases from escaping.
Gas particles (atoms, molecules) composing the atmosphere of a planet have a mass, therefore they are trapped by the gravitational field of the planet. This is not only true for giant planets but applies to all planets with atmosphere.
because if u have enough gas in one area it creates mass and causes it to stay in the gravity field of a planet

The gas giant planets have stronger gravity, which makes it harder for anything to escape, and are colder, which means that even with similar gravitational fields, gas molecules might not achieve escape velocity.
Because the mass of the planet holds it down.
