How to Download Any YouTube Thumbnail
YouTube stores thumbnails at multiple resolutions for every video. The highest quality is maxresdefault.jpg (1280×720), followed by hqdefault.jpg (480×360), mqdefault.jpg (320×180), and the small default.jpg (120×90). Paste any YouTube URL — youtube.com/watch?v=..., youtu.be/..., shorts, or embed URLs — and our tool extracts the video ID and fetches all available thumbnail sizes so you can choose and download.
