How much does Binance charge to convert?

I'm quite curious about the conversion fees on Binance. As a frequent trader in the crypto market, I often need to convert my assets between different cryptocurrencies. Could you please enlighten me on how much Binance charges for this service? Is there a fixed fee or is it based on the amount being converted? Additionally, do you offer any discounts or promotions for frequent converters? I would appreciate it if you could provide a detailed breakdown of the conversion fees and any associated costs. Thank you for your time and assistance.
