📥 OmniDown — HD Video Downloader (YouTube, TikTok, Instagram, X & More)

OmniDown is a powerful, lightweight, and modern userscript designed to extract and download online videos, audios, and images directly from your browser. It prioritizes direct high-definition local streams and offers seamless one-click fallbacks to Cobalt.tools or dedicated converters when streams are locked by DRM, CORS, or HLS limits.

🚀 What's New in Version 3.2.1?

TikTok Drawer Panel: The download menu on TikTok is now docked directly next to the control sidebar. It features a smooth, slide-out transition from behind the sidebar, straight right borders, and matches the exact height and frosted-glass style of the main controls.
TikTok ID Polling Sync: Intercepts console player logs with a 4-second protection lock to prevent rapid scroll events from overwriting the correct active video ID.
TikTok SPA Navigation: General URL polling keeps the sidebar, username, and video details perfectly synchronized across client-side (SPA) page changes without requiring reloads.
Cobalt Hash Prefill Fix: Updated Cobalt redirects to pass target URLs via hash fragments (#), enabling automated link pre-filling and download initiation on the Cobalt frontend.
Clean Link Copying (Instagram & YouTube): The "Copy Link" buttons now fetch clean post/reels page URLs (stripped of tracking metadata like ?igsh= or ?utm_source=) instead of temporary, expiring CDN server links.
Minimalist YouTube View: Disabled the redundant floating action button (FAB) on YouTube, keeping the player control bar clean and focused.

📸 Interface & Layout Guide

🎵 TikTok Feed Sidebar Integration

The live sidebar automatically binds to the active video in the viewport. Clicking "Download" slides out the quality selection menu from behind the sidebar. TikTok Sidebar Drawer

📺 YouTube Integrated Control Menu

A native vector SVG download button is injected directly inside YouTube's player control bar (ytp-right-controls). YouTube Control Integration

🌐 Floating Downloader for Other Websites

🛠️ Download Workflows

Direct Download (Local-First): Fetches and saves the media file directly inside your browser. It handles chunked downloading, signature solving, and shows a beautiful glassmorphic progress bar.
Cobalt Redirection: Pre-fills and opens Cobalt's clean interface using # parameters. Defaults to cobalt.tools but can be configured to any custom self-hosted instance.
External Fallback Resolver: Prompts redirection to trusted external conversion tools (like SnapTik, SSSTik, SaveFrom, FASTDL) when local streams are CORS-blocked or HLS-encoded.

🎮 Shortcuts & Customization

Ctrl + Alt + Shift + D: Open/close the download menu overlay.
Esc: Close open overlays or cancel active downloads.
Tampermonkey Menu Command options:
- 🌐 Change language (English, Portuguese, Spanish, Simplified/Traditional Chinese, Vietnamese).
- ⚙️ Configure custom Cobalt API URL or custom CORS Proxy.
- 🔘 Toggle Floating Action Button visibility.
- 🔘 Toggle Auto-Redirect (instantly go to fallbacks without confirmation prompts).

🔒 Security & Privacy

Zero Tracking: Processing runs 100% locally in your browser. No telemetry, no analytics, no third-party data tracking.
Trusted Types Compliant: Safe from XSS injection risks, using secure DOM generation APIs (createElement) instead of dangerous HTML parser APIs.
LRU Memory Guard: Automatic cleanup of cache maps ensures zero memory leaks when scrolling infinite feeds.
