About

YouTubeThumb.com is a free public browser tool. Paste a YouTube link and download the thumbnail YouTube already stored — 1280×720 when that file exists, plus the smaller sizes. Nothing is uploaded and there is no account.

The tool is ready as soon as the page loads. You do not install an extension. Images come from YouTube’s own thumbnail servers in this tab. It is for creators, editors, and anyone who needs the original cover file and then wants to get on with their day.

Public contact is contact@youtubethumb.com.
