Can you swap stETH to ETH?

Could you please clarify for me if it's possible to swap stETH to ETH? I've been hearing a lot about the benefits of staking Ether and receiving stETH as a reward, but I'm a bit uncertain about the process of converting it back to ETH. Could you explain the steps involved in this swap, and if there are any fees or risks associated with it? Additionally, I'd like to know if this swap can be done seamlessly or if there are certain platforms or exchanges that are preferred for this transaction. Thank you for your assistance in clarifying this matter for me.
