Why is the 1280×720 maxresdefault missing for some videos?

YouTube only generates maxresdefault for videos uploaded in HD (720p or higher). If a video was uploaded in SD or is older than 2013 (before YouTube's HD thumbnail era), only the smaller sizes exist. The tool shows 'Not available' for any resolution YouTube hasn't generated.

Does the tool download the video itself?

No — the tool only fetches thumbnail images from Google's public image CDN. Video downloading is a separate concern and, for most videos, is a terms-of-service violation on YouTube. This tool is scoped strictly to thumbnail retrieval, which is fair use for press and commentary.

Is it legal to use someone else's YouTube thumbnail?

The thumbnail is copyrighted by the video's creator. Fair-use exceptions (news reporting, commentary, criticism) often apply, but using the thumbnail in an unrelated marketing context typically requires permission. For editorial blog posts that discuss or review the video, attribution plus a backlink is standard practice.

Do the thumbnail URLs work for private or unlisted videos?

Unlisted videos, yes — they have publicly accessible thumbnails as long as you know the video ID. Private videos return a generic placeholder since private video thumbnails are not exposed on the CDN. Deleted videos return a 'video unavailable' image.

Does the tool support YouTube Shorts?

Yes — paste a /shorts/ URL or the 11-character ID and the tool fetches all available sizes. Shorts thumbnails are usually portrait aspect and YouTube may only generate mqdefault and hqdefault (no maxresdefault) for very short videos.

Can I pull thumbnails in bulk?

The UI is one video at a time. For bulk retrieval (e.g., an entire channel), the same URL format is fully documented: https://i.ytimg.com/vi/VIDEO_ID/maxresdefault.jpg — so a 10-line bash or Python script with a list of IDs will pull hundreds at once without rate limits, as long as you respect YouTube's fair-use policy.
