Thumbnail Grabber for YouTube

Download the thumbnail of the YouTube video you are watching, in every size up to 1280x720 plus the Shorts image. No tracking.

Grab the thumbnail of any YouTube video or Short in one click, straight from the video page. Open a video, click the icon, and the popup lists every thumbnail size YouTube stores for it: max resolution (1280x720), standard (640x480), high quality (480x360), medium (320x180), and the oar2 image (the vertical 9:16 thumbnail on Shorts; some regular videos carry a landscape variant there instead, and the popup labels it by its measured orientation). Each size has a Download button and a Copy URL button. Not on a YouTube page? Paste any link (watch, youtu.be, Shorts, embed, live) or a bare video ID into the box instead. Why this one: - It asks for nothing. The only permission is "activeTab", which lets the popup read the address of the tab you clicked it on. No "read and change your data on all websites", no content scripts, no background service worker, no analytics, no accounts. - It checks what actually exists. YouTube only creates the 1280x720 max-res file for HD uploads and custom thumbnails; for the rest, the request returns a 404 whose body is a 120x90 grey placeholder. The extension measures the real pixel width of every size and only offers the ones that are genuinely there, so you never save a grey square by mistake. This behaviour was measured on 8,664 public videos: https://thumbnailsgrabber.com/youtube-thumbnail-statistics - Images come directly from YouTube's own image host (i.ytimg.com).
