YouTube Thumbnail Grabber

Grab a YouTube video's public thumbnail — paste a link or video ID and view every available cover-image size, with a download link for each. Loads the public thumbnail image only; this is not a video downloader.

These are the public thumbnail images YouTube serves for any video at img.youtube.com/vi/ID/…. Prefer the max-resolution image when it loads; sizes a video doesn't have are skipped automatically. This shows the cover image only — it is not a video downloader — and the thumbnail belongs to the video's owner, so use it responsibly. Nothing is uploaded.

How to grab a YouTube thumbnail

Paste the full video URL (youtube.com/watch?v=… or a youtu.be/… short link) or just the 11-character video ID. The tool reads the id, loads each public thumbnail size and gives you a download link for every image that exists.

Getting the highest quality

Always prefer the max-res image when it loads — it is the sharpest. If max-res is blank, the video may not have one, so fall back to the HD (sddefault) or high-quality (hqdefault) size, which every video provides.

Questions

What exactly does this download?
Only the public thumbnail image. YouTube serves each video's cover image at fixed URLs like img.youtube.com/vi/VIDEO_ID/maxresdefault.jpg. This tool builds those URLs from the id you paste and shows the images with a download link — it does not download the video itself.
Which sizes can I get?
YouTube exposes several thumbnail sizes: maxres (up to 1280×720), standard (640×480), high (480×360), medium (320×180) and the default (120×90). Not every video has a max-res image, so use the largest one that loads.
Can I use the thumbnail freely?
The image belongs to the video's owner and is protected by copyright. Grabbing it for reference, a preview or fair-use commentary is one thing; republishing someone else's thumbnail as your own may infringe their rights. Use it responsibly.
