Looking for ways to change the size of the Facebook Video Preview? I recently discovered Enlargeify and use it regularly now for Facebook videos. It’s a cool new free tool that allows users to take an existing YouTube link and convert it into a Facebook friendly format (i.e. larger Facebook video preview image) without the need to upload directly to Facebook. So not only does it give you a larger video preview (which can lead to more views), but it also saves you from having to upload twice to YouTube and Facebook.
