Can I swap ERC-20 to ETH?

As a keen investor in the cryptocurrency space, I'm curious about the feasibility of swapping ERC-20 tokens for ETH. ERC-20, being a popular token standard on the Ethereum blockchain, allows for a wide range of decentralized applications and services. However, as market conditions change and my investment strategies evolve, I'm considering liquidating some of my ERC-20 holdings and reallocating them to ETH, the native currency of the Ethereum network. Could you elaborate on the process involved in such a swap? Are there any specific platforms or exchanges that facilitate such transactions efficiently and securely? I'd appreciate any guidance you could offer on this matter.
