About

Unthumb - See What Videos Actually Look Like

YouTube thumbnails are designed to grab your attention, not to show you what's in the video. Exaggerated faces, misleading images, and clickbait visuals make it harder to decide what's worth watching.

Unthumb hides and replaces every thumbnail on the YouTube homepage with an actual frame from the video pulled directly from YouTube's own storyboard data. No guessing, no AI, no
third-party services. You see a real moment from the video before you click.

Features:
  • Automatically replaces homepage thumbnails with real video frames
  • Choose where in the video to grab the frame, most-watched, percentage (default is 30%), or let it pick a random spot for each video
  • Works with YouTube's infinite scroll, new thumbnails are replaced as they appear
  • Lightweight and fast, no external requests beyond YouTube itself
  • Configurable fallback when a frame can't be loaded: show the original thumbnail or a clean black box

Stop letting thumbnails make decisions for you. Unthumb gives you an honest preview of every video so you can browse YouTube on your own terms.
