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

Fast, secure, and lightweight userscript to download online videos locally, or redirecting to dedicated external tools when local streams are blocked by CORS/DRM/HLS limits.

Supported Websites & Platforms

  • YouTube: Multiple quality options (Shorts, Embeds, watch videos, audio, subtitles/SRT).
  • TikTok & Douyin: Watermark-free MP4 extraction with fallback options.
  • Instagram: Feed, Reels, Stories, and HLS/Blob streams.
  • X (Twitter): Direct MP4 URLs extractor.
  • Facebook & Threads: Embedded video parsing.
  • Pinterest, Snapchat, TED: Local extraction where possible and site-specific external converters.
  • Spotify: Easy search and download redirects.

Advanced Features

  • Strict Iframe Context Guard: Employs context checking to prevent multi-initialization inside nested ad frames or extensions, restricting global FAB creation to the top-level window.
  • Local-First & Multi-Proxy Download: Downloads videos directly inside your browser whenever possible, utilizing CORS proxies sequentially on network failures.
  • Robust Download Cancellation: Cancels running and queued downloads cleanly, ignoring asynchronous callbacks from aborted connections.
  • Robust JSON Parsing: Uses a bracket-balancing algorithm to extract raw player response variables safely without matching inner strings or nested formats.
  • YouTube base.js Signature Deciphering: Built-in dynamic algorithm decryption for protected streams (including embed and Shorts fallbacks) with automatic redirection fallback recovery when decryption fails.
  • Strict Performance & Execution Scopes: Restricts execution to supported domains only and leverages mutated node batch parsing to eliminate CPU spikes. Backed up with highly relaxed 5-minute idle scan cycles.
  • Native YouTube Player Controls Button: Injects a clean, native SVG download button directly inside YouTube player controls.
  • Clean Memory Management: Maps file sizes and embed configurations inside size-bounded LRU caches to prevent long-term memory leaks.
  • Privacy Confirmations: Never triggers external redirects without explicit user confirmations.
  • Minimized Player & Parallel Downloads: Beautiful, glassmorphic download manager overlay which supports desktop minimization, custom scrollbars, active filename labels, sequential toast queues, and pulsating download indicators.

Controls

  • Floating Button: Appears automatically when a video is loaded on the page (pulses red when downloading).
  • Keyboard Shortcuts:
    • Ctrl + Alt + Shift + D: Open download menu (can be toggled in menu commands).
    • Esc: Close download menu / cancel download.
