Zoom to Fill - Ultrawide Video is a Chrome extension that removes black bars from videos on popular streaming platforms like Netflix, Amazon Prime, and YouTube by changing the video aspect ratio to ultrawide. It works on most websites and is especially useful for ultrawide screens, but can be used on any resolution. The extension provides a player button for easy zooming and scrolling to adjust the zoom level. It also offers a popup with more options and features, manual zoom adjustment, persistent mode, and keyboard shortcuts.
