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.
