YouTube Thumbnail Downloader

Up to four for every video: **Max** (1280×720, 16:9), **Standard** (640×480, 4:3), **High quality** (480×360, 4:3), and **Medium** (320×180, 16:9). The max-resolution thumbnail is the same image YouTube shows in the embed player. Lower resolutions are auto-generated by YouTube at upload time.

YouTube only generates `maxresdefault.jpg` for videos uploaded after late 2012 *and* when the original frame was at least 720p. Older videos and very-low-resolution uploads simply don't have it. The tool marks unavailable resolutions clearly so you can grab the next-best one.

All of them: standard watch URLs (`youtube.com/watch?v=...`), short URLs (`youtu.be/...`), Shorts (`youtube.com/shorts/...`), embeds (`youtube.com/embed/...`), live (`youtube.com/live/...`), music.youtube.com, m.youtube.com, or just the bare 11-character video ID.

Thumbnails are hosted on YouTube's public CDN (`img.youtube.com`) with no authentication required — you're not bypassing any access control. Downloading for personal reference, education, or research generally falls under fair use. Republishing as your own without credit, or using a thumbnail in a way that implies endorsement, may not. As with all copyrighted content, consider the source and intended use.

Common uses: making a video roundup post, building moodboards, citing a video in a presentation, archiving research, generating thumbnails for embeds in a CMS that doesn't auto-extract them, or grabbing reference frames for video work.

Yes — YouTube's CDN caches thumbnails aggressively. If the channel later changes the thumbnail, you may see the old one for up to 24 hours. To force a refresh, append `?t=1` to the image URL (the tool's download buttons don't do this — they fetch whatever's currently served).

Not extracted by this tool — that requires the YouTube Data API and an API key. For a thumbnail-only flow, this is faster and doesn't need authentication.

Unlisted: yes — anyone with the video ID can access the thumbnail. Private: no — YouTube serves a placeholder image instead. Age-restricted: thumbnails are usually still accessible since they're not graphic content.
