The YouTube thumbnails help you attract viewers to click on your video link. So, why not use an animated thumbnail for making your link even more impressive. Enter your video URL in the ‘Find Animated Thumbnail’ and press enter. If the URL does not work, you can also paste the source code of the page that lists the YouTube video. It would populate all the relevant animated thumbnails for your video. It is very safe to use. The best part is that you can download the thumbnails in the desired resolution you wish to with various options to choose from.
