Understanding YouTube Thumbnail Resolutions

YouTube provides up to three standard thumbnail sizes:

Max Resolution (maxresdefault) – 1920×1080 pixels (Full HD) or 1280×720 (HD). Only available for videos uploaded in high quality.
Medium (mqdefault) – 320×180 pixels. Good for general use.
Small (default) – 120×90 pixels. Lowest quality, fastest to load.

If a video lacks the max resolution thumbnail, our tool automatically tries a fallback (hqdefault) before marking it as unavailable. This ensures you always get the best possible image.

Frequently Asked Questions

Yes! 100% free with no hidden fees. Download as many thumbnails as you want, no sign‑up required.

No. The tool only works for public YouTube videos. Private or unlisted videos are not accessible via the public thumbnail API.

Not all videos have a maxresdefault image – it’s generated only for higher‑quality uploads. Older or low‑resolution videos may only have medium and small thumbnails.

Absolutely not. All processing happens in your browser. We never see or store your URLs or downloads.

Thumbnails are downloaded as .jpg files – universally compatible with all devices and software.
