YT-XL is a Chrome add-on developed by Manu Mehrotra that allows users to generate Youtube video links with bigger thumbnails for sharing on Facebook. This free tool aims to enhance the visual appeal of shared Youtube videos on Facebook by providing larger thumbnails.

To use YT-XL, simply go to the Youtube video page on youtube.com and click on the Youtube-XL icon. This will generate a sharable link with a bigger thumbnail specifically optimized for Facebook. Alternatively, you can utilize the "Share On Facebook" button provided by the add-on to share the video directly on Facebook.

It is worth noting that the Youtube-XL icon will be disabled if you are not on a youtube.com page that contains a video. This ensures that the add-on is only active when relevant content is present.

With YT-XL, users can effortlessly enhance the visual impact of Youtube videos shared on Facebook, making them more engaging and eye-catching for viewers.
