Zero-Knowledge Architecture
FileDex uses WebAssembly to run conversion engines directly in your browser. Your files are never uploaded to any server. You can verify this yourself:
- SHA-256 hash your file before and after — proves no modification by external parties.
- Network monitor via PerformanceObserver — shows zero file-related network requests.
- Open DevTools Network tab — see for yourself that nothing uploads.
Provable privacy, not just promised.
