Where can I swap ETH to USDT?

I'm new to the world of cryptocurrency and I'm looking to swap some Ethereum (ETH) for Tether (USDT). Could you possibly recommend a secure and reliable platform for this transaction? I'm a bit concerned about the safety of my funds and want to make sure I'm using a legitimate exchange. Additionally, if there are any fees or commissions involved, it would be great if you could provide some insight into those as well. Thank you for your help!
