YouTube Up Next Thumbnail Preview

Test your YouTube thumbnail with Thumbnail.live, crafted from the ground up to be the best online YouTube thumbnail previewer.

This tool allows you to test your YouTube thumbnail to see how it looks when the user is viewing another video.

You can submit links to your thumbnail and avatar if its already online and save the hassle of having to find them in your files.

Everything you input (excluding uploaded files) is stored on your browser, meaning you don't have to re-enter your avatar link and username every time.

Uploaded files are not stored, so if you want to retain your thumbnail and avatar, you always have the option to use links instead.
