What Is a YouTube Thumbnail?

A YouTube thumbnail is the preview image that represents a video before you play it. It’s the first thing viewers see when browsing YouTube, making it a powerful tool for grabbing attention and getting clicks.

Think of it like a mini movie poster—a good thumbnail tells viewers what your video is about in a single glance.

However, don’t use thumbnails commercially (e.g., in your own videos or products) unless you have the creator’s permission or the image is royalty-free.
