Thumbora — YouTube Thumbnail Viewer

About

Thumbora — YouTube Thumbnail Viewer is a simple, privacy-friendly Chrome extension that lets you preview or copy any YouTube video’s thumbnail directly from your right-click menu. Perfect for creators, designers, and marketers who need fast access to clean, high-quality thumbnails.   

Key Features:

 • View Thumbnail – Instantly preview the video’s thumbnail in a clean, centered pop-up.
 • Copy Thumbnail URL – Copy the thumbnail link for use in social posts, blogs, or design tools.
 • Open in New Tab – Quickly open the thumbnail in its full-resolution version.

Why Use Thumbora?
