Where can I convert USDT to USDC?

I'm seeking some clarity on the process of converting USDT to USDC. Could you please advise me on where I can carry out this conversion efficiently? I've been hearing about various platforms and exchanges, but I'm not entirely sure which one is the most reliable and suitable for my needs. Additionally, I'm also interested in understanding the fees and charges associated with this conversion, as well as the estimated time it might take to complete the transaction. Could you provide me with some insights on these matters? Your guidance would be greatly appreciated as I'm new to the cryptocurrency space and still navigating through its complexities.
