Video Transformer is a Chrome extension designed to enhance the video playback experience by optimizing how videos fit within the browser viewport. Currently in its alpha stage, this free tool focuses on transforming a selected video to fill the screen without any distracting elements. Users can utilize commands to fit, fill, or stretch the video, making it particularly useful for platforms like YouTube, with plans for broader compatibility on other video domains in the future.

This extension works in conjunction with another tool called Viewport, allowing users to convert a standard browser window into a popup window for a more immersive viewing experience. Additionally, it offers options to manipulate video orientation, including horizontal and vertical flipping, ensuring that users can achieve the desired visual presentation. The extension is based on adapted code from existing projects, emphasizing its utility and adaptability.
