YouTube Thumbnail Downloader

Everything YouTube publishes for the video: max resolution (1280×720), standard (640×480), high quality (480×360), medium quality (320×180) and the 120×90 default. Only the sizes that actually exist are offered — older or low-resolution uploads often have no 1280×720 version, and the tool says so by leaving it out rather than handing you a grey placeholder.

YouTube captures three stills from every upload — near the start, the middle and the end — and uses them as the automatic thumbnail choices in the uploader’s studio. They are public images at 1280×720, so you can save them here too. Very new uploads sometimes do not have them yet.

Yes — watch links, youtu.be short links, Shorts, embed and live links all work. You can also paste just the eleven-character video ID.

YouTube only makes a 1280×720 thumbnail when the uploaded video or the custom thumbnail is large enough. For older and lower-resolution uploads the biggest you can get is 640×480 or 480×360, which is what the tool offers.

JPEG, exactly as YouTube serves it — no re-encoding, no watermark, no resizing. The filename carries the video ID and the size so a folder of them stays sortable.

No. The sizes are checked by loading the images in your browser straight from YouTube. The download passes through a small proxy only because YouTube’s image host does not allow browsers to save its files directly; nothing is kept.

The image belongs to whoever made it. Saving one for reference, study or a review is normal use; putting it on your own video or product needs their permission.
