Stretch | YouTube Windowed Fullscreen

Windowed fullscreen for YouTube: video fills the page, UI hidden, browser stays windowed. All languages supported.

Turn the YouTube player into a clean, page-filling view without putting your browser into fullscreen. Stretch adds a button directly to the YouTube player controls, next to the native fullscreen button. Click it and the video fills the whole page while the YouTube header, recommendations, title, comments, chat and other page elements are hidden. Your tabs and address bar stay available, so you can keep browsing, switch tabs, or move the window to another monitor. Features: • Windowed fullscreen: the video fills the page, the browser stays windowed • One-click toggle in the YouTube player controls • Hides the YouTube page UI for a clean viewing experience • Native player controls, captions, quality and settings remain available • Press Esc or click the button again to exit • Automatically leaves windowed mode when you enter native fullscreen • Lightweight Manifest V3 extension with no background service • No tracking, no analytics and no data collection Languages: Tooltips are localized in 25 languages: English, French, Spanish, Portuguese (Brazil and Portugal), Chinese (Simplified and Traditional), Hindi, Bengali, Urdu, Tamil, Arabic, Persian, Turkish, German, Dutch, Italian, Polish, Ukrainian, Russian, Japanese, Korean, Vietnamese, Thai, Indonesian, Filipino, and Swahili. Any other browser language falls back to English. Permissions and Privacy: The extension requests access to youtube.com only, so it can add the button and adjust the player layout. It does not collect, store, or transmit personal data. Stretch is an independent project and is not affiliated with, endorsed by, or sponsored by YouTube or Google.
