YouTube Thumbnail Viewer (YTTV)

Userscript that allows you to view (and copy / download) a YouTube video's thumbnail easily from within its description


Current Limitations:

  • Due to YouTube's wonky ass code, if you switch to another video without going back to the home / subscriptions / explore page, you will need to reload the page so YTTV can re-grab the thumbnail, else it will just give you the thumbnail of the first video you've watched.
    I don't know if there's a way I can fix this so just be aware that this happens.
  • YouTube uses the WEBP format to store thumbnails on modern browsers, so the opened and downloaded thumbnails will usually also be in this format (old videos might still only have JPG or PNG).
    There's nothing I can do to convert WEBP to PNG or JPG, so you will have to use a converter like ezgif.com



Installation:

  1. Install a userscript manager extension

    GreaseMonkey: Firefox
    TamperMonkey: FirefoxChromeSafariOperaEdge

  2. Go to this page to install or update the userscript



Usage:

Expand the video description and scroll to the bottom.
You will find a line with two links:

  • Open: This link opens the thumbnail in a new tab. From there, you can freely copy or download it yourself by right-clicking.
  • Download: Prompts you to download the thumbnail



Planned features:

  • New link to open the thumbnail in a small <iframe> for copying without having to open in a new tab
  • A way to select a specific thumbnail resolution
