How to change wrapped sol to sol?

Excuse me, I'm a bit confused about the process of converting wrapped SOL to SOL. Could you please elaborate on the steps involved in this conversion? I've heard that wrapped SOL is essentially a tokenized version of SOL that allows it to be used on different blockchains, but I'm not sure how to go about swapping it back to the native SOL coin. Is there a specific exchange or platform that I should use? Additionally, are there any fees associated with this conversion, and how long does the process typically take? Thank you for your help.
