No, this is not about lazy loading. We are talking about image compression only, as images are an important part of your page load (20% on average). Every byte counts when you want to get a 100% Google Lighthouse Score. I was happy to find that Boris Smus did some great ground work on this topic, suggesting that a ‘highly compressed 2x image is smaller in size and looks better than the uncompressed 1x image’.| Hugo Codex
