PW DRM Downloader

Browser-based decryption — your server uses zero bandwidth for video data

CDN Direct DownloadIn-Browser DecryptionZero Server Bandwidth
How It Works

1. Server only fetches the tiny MPD manifest (~10KB) + DRM key (~1KB)

2. Your browser downloads encrypted segments directly from CDN

3. Your browser decrypts segments using WebCrypto API — no server involved!

4. Decrypted video/audio saved to your device. Merge with ffmpeg if needed.
