🚀 YouTube Video Downloader - Tenzaa (Global Edition)

https://tenzaa.com/youtube

The fastest, most lightweight, and TrustedHTML-compliant downloader for YouTube. Integrated directly into your player interface.

Tenzaa Global Downloader adds a sleek, native-looking red button to the YouTube action bar, allowing you to jump straight to high-speed conversion for any video. No bloat, no tracking, just pure functionality.

✨ Key Features

⚡ Instant Access: One-click redirection to Tenzaa’s high-speed processing servers.
🌍 104 Languages Supported: The UI and button labels automatically adapt to your browser's language setting.
💎 Ultimate Quality: Supports all available resolutions including 4K (2160p), 2K (1440p), 1080p (Full HD), and 720p.
🎵 MP3 & Audio Extraction: Easily convert any music video into high-quality MP3 or M4A audio files.
🛡️ Privacy & Security: Built with TrustedHTML standards to bypass strict Security Policies (CSP). No personal data collection.
📱 2026 Layout Ready: Fully compatible with the latest YouTube "Ambient Mode" and "Action Bar" updates.

📖 How to Use

🛠️ Technical Specifications

Manager Compatibility: Works perfectly with Tampermonkey, Violentmonkey, and Greasy Fork's native installer.
Engine: Uses native DOM injection (NS-SVG) to ensure the button renders even on sites with high security restrictions.
Performance: Zero impact on page load speed; the script only activates when the action bar is detected.
