YouTube Fit to Screen — Chrome Extension
Last updated: June 12, 2026
YouTube Fit to Screen is a browser extension that adds a button to the YouTube video player, allowing videos to fill an ultrawide (or any) screen by entering fullscreen and cropping the video with CSS. The extension operates entirely within your browser and does not collect, transmit, or store any personal data.
This extension collects no data of any kind. Specifically:
The extension declares no browser permissions beyond a content script that
runs only on https://www.youtube.com/*. It manipulates the
YouTube player's DOM to inject a button and CSS — nothing more.
This extension does not integrate with or send data to any third-party service.
If the extension ever changes in a way that affects data handling, this policy will be updated and the "Last updated" date will reflect the change.
