Zoom To Fill

Zoom To Fill removes black bars from videos and helps content fill your screen more naturally. It is especially useful on ultrawide displays and also works well when older aspect ratios leave unused space on standard screens.

No more distracting black bars. The extension works with most modern video players on the web and is designed to be simple, fast, and easy to use.

How to use

Go to any page with a video
Click the Z button that appears on the player, or open the extension popup
Press Alt+Z at any time to toggle zoom on or off
