ChanVault Pro — 4chan Gallery & Media Suite

Full gallery view, bulk downloader, duplicate detector, thread watcher, and offline 404 vault.

Turn chaotic, linear 4chan threads into a clean, modern media workstation. ChanVault Pro extracts every full-resolution image and WebM from any thread on 4chan and 4channel into a responsive, high-performance gallery. Built for digital archivists, general board followers, and media collectors. ⚡ CORE FEATURES: 🖼️ Responsive Full-Viewport Gallery • View every image and WebM in a thread tiled in a dark-mode grid. • Native uncropped aspect ratios (no squished photos or awkward letterboxing). • Toggle between "Fit" (full uncropped view) and "Fill" (square grid) anytime. • HD Master Mode: Browse uncompressed master files with smooth lazy-loading. ⬇️ One-Click Bulk Exporter • Download an entire thread's media library with a single click. • Automatically formats filenames cleanly prefixed with the original Post ID (e.g. "5274448_wallpaper.jpg"). • Organizes downloads into dedicated subfolders (`Downloads/4chan_{board}_{thread}/`). • Throttled queue controller prevents Chrome download rate-limiting or freezing. 💾 Offline 404 Vault (Save-Before-404) • 4chan threads die fast. Save complete threads and media directly into your local browser storage before they get pruned. • Access and browse your archived threads even after they 404 from 4chan's servers. • Built-in full-screen lightbox to inspect master resolutions offline. 🔍 Perceptual Repost & Duplicate Filter • Powered by client-side difference hashing (dHash). • Scans and identifies duplicate memes, reaction images, and reposts in large 500+ post general threads. • Filter out spam with one click so you only see original media. 👁️ Multi-Thread Background Watcher • Track several threads across different boards without keeping dozens of browser tabs open. • Periodically polls 4chan's official API in the background. • Get badge counter updates and native desktop notifications when new media lands. 📌 Cross-Thread Collections (Pinboard) • Pin individual photos and WebMs from any thread into custom tagged collections (e.g., "Wallpapers", "Reaction GIFs", "Design Inspo"). • Stored persistently in your browser with full offline access. --- 🔒 PRIVACY & PERMISSIONS: • 100% Client-Side: ChanVault Pro runs entirely inside your browser. No tracking, no external analytics, and no third-party telemetry. • Safe & Lightweight: Only requests access to 4chan/4channel domains and storage APIs necessary to save your local vault.
