YouTube Thumbnail Downloaders — All Sizes, One Click

YouTube publishes each cover as a small ladder of images, and only some rungs exist for any given video. These three tools take a link — watch, Shorts, live, youtu.be or a bare video ID — and return the sizes that genuinely exist, with a one-click download for each. Start with the downloader when you have one video and want everything, use the size-first page when the destination layout decides the resolution, and reach for the grabber when you are on a phone and want the image in three taps.
