How does the YouTube Thumbnail Downloader work?
Paste a YouTube video URL and the tool extracts the video ID, then checks YouTube's own image host for the max resolution, standard, high, medium, and default thumbnail images available for that video.

FAQ
YouTube Thumbnail Downloader FAQ
Is my video URL sent to a server?
No. Everything runs in your browser. The tool only requests thumbnail images directly from YouTube's img.youtube.com host and never sends your URL to a TripleW Tools server.
Why is the max resolution thumbnail sometimes missing?
Not every video has a 1280x720 maxresdefault image, especially older or lower-resolution uploads. The tool automatically checks each size and only shows thumbnails that actually exist for that video.
