About YouTube Thumbnails
Thumbnails are the face of a video. They are often the first thing viewers see and can determine whether people click or scroll past. Our tool helps you download these images in the highest available resolution for your projects, archives, or inspiration.
Why is 4K not showing?
MaxRes (1080p/4K) thumbnails are only available if the creator uploaded a high-resolution image. If a video is old or low quality, YouTube might only serve standard quality thumbnails.
