Why does it cost so much to swap on Uniswap?

Excuse me, could you please explain why the transaction costs on Uniswap are so high? I've noticed that swapping tokens can be quite expensive, and I'm curious to know if there's a specific reason behind this. Is it due to the decentralized nature of the platform, or are there other factors that contribute to the higher fees? It would be great if you could clarify this for me. Thank you.
