How much does KuCoin charge for convert?

Excuse me, could you please clarify for me how much KuCoin charges for conversion services? I'm considering using their platform for some cryptocurrency transactions and would like to know if their fees are competitive or not. I've heard that different platforms have varying fee structures, so I'm wondering if KuCoin's charges are reasonable and transparent. It would be great if you could provide me with some specific details on this matter. Thank you in advance for your help.
