Which file formats does PornGIF.live keep?

Each clip is stored three ways: the source GIF itself, a copy as MP4 video, and WebP copies in a handful of sizes. Same clip, different wrappers. MP4 is the lightest for the quality, so previews use it; GIF plays almost anywhere but is the heaviest; WebP falls in between and is served whenever your browser supports it. The page picks the best fit for your device on its own, and the download button always hands you the original.
