What is the YouTube Thumbnail Downloader? Have you ever wanted to download a YouTube video thumbnail for any purpose? Here you can! Just enter the video ID and the project will give you a link that you need to open up in a new tab, and the thumbnail will be there. This only works for public and unlisted videos. Private videos aren't public, so you can't get their thumbnail. What is a YouTube video ID? The ID is the text in a YouTube video link after "watch?v=" ex: https://www.youtube.com/watch?v=dQw4w9WgXcQ. So in this case, the video ID would be dQw4w9WgXcQ.
