What Is a YouTube Thumbnail?
A YouTube thumbnail is the small preview image that represents your video before someone clicks on it. Think of it as your video’s first impression — the visual hook that convinces viewers to watch.
When uploading a video, YouTube generates three random thumbnails, but creators can also upload a custom thumbnail to better reflect their content and branding. A well-designed thumbnail can dramatically improve your click-through rate (CTR).
