FAQ

Do I need a YouTube API key?

No. Thumbnails are publicly accessible static files hosted by YouTube's CDN — no API key or login needed.

What thumbnail resolutions are available?

We provide Max Resolution (up to 1280×720 HD), Standard Quality (480×360), and Medium Web (320×180). Not all videos have all sizes.

Why is the HD thumbnail not available for some videos?

The maxresdefault thumbnail is only generated for videos uploaded in HD. Older or low-resolution videos may only have the standard thumbnail available.
