The simplest way to download YouTube thumbnails.
Tube Fetch is a free tool that lets you extract YouTube video thumbnails in all five available resolutions. Paste any YouTube URL and instantly see every thumbnail from default (120x90) to maxresdefault (1280x720).
Every YouTube video has predictable thumbnail URLs hosted at img.youtube.com. Tube Fetch extracts the video ID from your URL, constructs all five thumbnail URLs, and fetches video metadata via YouTube's oEmbed API. No YouTube Data API key is required.
Paid plans include REST API access with JSON responses. Use it to integrate thumbnail extraction into your own apps, workflows, or content pipelines. View plans for details.
Tube Fetch has no display ads and doesn't sell your data. The service is funded by optional paid plans.
