What is Thumbnail Test?

Thumbnail Test is a tool designed to help creators optimise their video thumbnails before publishing. It allows you to test how your thumbnails perform and appear across different devices and contexts, showing you how they'll look on YouTube, social media, and other platforms. The tool helps identify whether thumbnails are clear, readable, and eye-catching at various sizes. This is particularly useful for content creators, YouTubers, and social media managers who want to maximise click-through rates and ensure their thumbnails remain effective when scaled down or displayed in feeds.
