Can USDT be transferred to USD?

I'm a bit puzzled about a concept related to cryptocurrency. Could you please help me understand? I've heard about USDT, which seems to be a stablecoin pegged to the US dollar. But I'm not quite sure if it can be converted directly into actual USD. Is there a way to do this? Could you explain the process, if it's possible? Also, are there any fees or limitations involved in such a transfer? Your clarification would be greatly appreciated. Thank you for your time and assistance in this matter.
