The Predictable Thumbnail CDN — Under the Hood
YouTube serves covers from i.ytimg.com at fixed paths: /vi/<id>/maxresdefault.jpg, sddefault.jpg, hqdefault.jpg and so on. Once the 11-character video ID is extracted from any URL shape, every resolution is a deterministic address — which is why this tool needs no API key and no upload.
