Paste a video or Shorts link and get every size YouTube stores for it — up to 1280 × 720 — ready to save. Runs in your browser; nothing is uploaded or stored.
Every public YouTube video has its thumbnail stored at a few fixed sizes. The largest one only exists when the creator uploaded a big enough image, which is why some videos top out at 640 × 480.
Full HD (1280 × 720) is the size YouTube recommends for custom thumbnails. Standard and High versions are letterboxed 4:3 crops, so they show black bars at the top and bottom.

YouTube only creates the 1280 × 720 version when the uploaded thumbnail or video was at least that large. Older and low-resolution uploads stop at 640 × 480 or smaller.
Yes. Shorts links work the same way; the thumbnail is the frame or cover image YouTube stores for that Short.
Viewing and saving a public image for personal reference is common, but the thumbnail is the creator's work. Don't republish someone else's thumbnail without permission.
No. It runs in your browser and loads the image directly from YouTube's image server. Nothing is stored and no sign-up is needed.
