cd compress.lol

# Install dependencies
npm install

# Start development server
npm run dev

🎯 How It Works

Smart Compression Algorithm

1. Video Analysis: Automatically detects motion levels, resolution, and encoding characteristics
2. Target-Based Encoding: Calculates optimal bitrates and settings for your target file size
3. Motion-Aware Settings: Adjusts encoding parameters based on content complexity
4. WebAssembly Processing: Uses FFmpeg compiled to WASM for native-speed compression

Compression Targets

• 8 MB – Ultra compression for sharing
• 25 MB – High compression for social media
• 50 MB – Medium compression for email
• 100 MB – Low compression for archival

🛠️ Development

npm run dev        # Development server
npm run build      # Production build
npm run preview    # Preview production build
npm run check      # TypeScript check
npm run format     # Prettier formatting

FFmpeg Integration

The app uses FFmpeg.wasm for video processing:

• Core: ffmpeg-core.js – Main FFmpeg engine
• WASM: ffmpeg-core.wasm – WebAssembly binary
• Worker: ffmpeg-core.worker.js – Background processing

📱 Browser Support

• Chrome/Edge: 90+
• Firefox: 89+
• Safari: 15+

Requires WebAssembly and SharedArrayBuffer support.

File Size Limits

• Maximum file size: 2GB (browser limitation)
