Because it helps them move through the water faster.
Further information:
Penguins spend much of their time in the sea, which is their source of food. Flippers are needed to enable them to swim, in order to catch their food. Penguins' wing bones are fused straight, rather than angled like a flying bird's, and this has the effect of making the wing rigid and powerful, like a flipper. The small wings and a streamlined body shape are ideal for diving in water, and also give the penguin extra speed when swimming.

Why do penguins need to swim?
Penguins need to swim to catch their food, which mainly consists of fish and krill. Swimming also helps them escape predators and navigate efficiently in their marine environment. Penguins are highly adapted to swimming, with their streamlined bodies and flipper-like wings helping them move gracefully underwater.
How are penguins adapted to life in the sea?
Penguins have waterproof feathers that keep them insulated and buoyant in cold waters. Their streamlined bodies and flipper-like wings help them navigate through the water with precision. Specialized wing muscles allow them to "fly" underwater, and their thick layer of blubber provides extra insulation.
Why do penguins swim so fast?
Penguins have adapted to be fast swimmers in order to catch fish, their primary food source. Their streamlined bodies and flipper-like wings help them navigate through the water with agility and speed. Additionally, being able to swim quickly helps penguins evade predators such as seals and orcas.
