All processing happens 100% in your browser. When you convert images, PDFs, or any files, they never leave your device. We don't have servers that store or process your data.

No. We don't store your files, conversion history, or any personal data. Some tools use browser localStorage for temporary settings (like theme preference) or daily usage limits, but this stays on your device only.

1. Client-side processing only
2. No backend servers for file handling
3. No analytics that track individual users
