Where can I convert BTC to BNB?

I'm looking for a reliable platform where I can convert my Bitcoin (BTC) to Binance Coin (BNB). Could you recommend a few options that offer competitive exchange rates and low transaction fees? It's essential for me to find a secure and trusted exchange that ensures a smooth and efficient conversion process. I've heard about some exchanges, but I'm not sure which one would be best for my needs. Could you provide some insights or advice on this matter? It would be greatly appreciated if you could also mention any additional factors I should consider while choosing an exchange for this conversion.
