Can I switch BNB to ETH?

I'm currently holding some BNB, but I've been eyeing ETH for quite some time now. I'm wondering, is it possible to switch my BNB to ETH? I'm not really sure how the process works, and I'm a bit concerned about the risks involved. Could you please explain to me the steps I need to take and any potential pitfalls I should be aware of? I'd also like to know if there are any fees associated with this kind of transaction, and how long it might take for the switch to be completed. Your advice would be greatly appreciated.
