Can you swap WETH for ETH?

Could you please clarify for me, is it possible to exchange WETH for ETH? I've been hearing a lot about these cryptocurrencies and I'm trying to understand the process better. I'm aware that WETH stands for Wrapped Ethereum, but I'm not entirely sure how the swapping mechanism works. Is there a specific platform or exchange that facilitates this swap? Also, are there any fees involved in the process? Would it be advisable to do this swap at the current market conditions? Thank you for your assistance in clarifying this matter.
