About ThumbFetch

ThumbFetch does one job: given a YouTube link, it shows you the video's thumbnail in every size YouTube publishes, ready to download.

Why it exists

YouTube stores every public video's thumbnails on a public image CDN at addresses anyone can construct from the video ID. Plenty of sites wrap that fact in sign-up walls, watermarks, or download managers. It also turns out many of them hand you a 120×90 placeholder while calling it "HD", because they never check what actually came back. ThumbFetch is the plain version: no account, no watermark, no intermediary server — and a size check that labels a placeholder a placeholder.

How it works, exactly

• Your link is parsed in your browser down to its 11-character video ID. Nothing you paste is sent anywhere.
• The page builds the five standard CDN addresses (img.youtube.com/vi/<id>/<size>.jpg) and your browser loads those images directly from YouTube.
• Each loaded image's true pixel dimensions are compared with the size it claims to be, so missing sizes are reported honestly instead of faked.
• Downloads save straight from YouTube to your device; if your browser blocks the direct save, the image opens in a new tab for a manual save.

What it is not

ThumbFetch is not affiliated with YouTube or Google, does not download videos, and cannot reach private videos. It also doesn't grant any rights over the images: thumbnails belong to their creators, and the site says so wherever downloads happen. See the creators page for the research-vs-reuse line.

The fine print

ThumbFetch is a free static site. A Pro tier ($9/month) is planned for heavy creator workflows like channel-wide audits and playlist ZIP export; the core downloader stays free. Privacy details: privacy page.
