It presents side-by-side comparisons of images in PNG, WebP-lossless, and WebP-lossy (with alpha) formats in one gallery and JPEG vs. WebP in another. Users can view these image comparisons in the provided links, showcasing the visual results of WebP's lossless and lossy compression and how it handles alpha transparency. The key action is viewing and comparing images in different formats.\n"]]
