Your Privacy is Our Priority

ConvertAll.io was built from the ground up with privacy as the core principle. Unlike traditional online converters, your files never leave your device. Here's exactly how we protect your privacy.

🔐 Local Processing Explained

What is Local Processing?

Local processing means all file conversions happen directly in your web browser, on your own device. This is fundamentally different from traditional online services that upload your files to remote servers.

Traditional Online Converters: 1. You upload your file to their server 2. Their server processes your file 3. You download the result 4. ❌ Your file exists on their server during processingConvertAll.io: 1. You select your file (it stays on your device) 2. Your browser processes the file locally 3. You download the result immediately 4. ✅ Your file never leaves your device

Technical Implementation

  • WebAssembly (WASM): High-performance conversion libraries run directly in your browser
  • Client-Side JavaScript: All processing logic executes on your device
  • HTML5 File API: Files are accessed locally without uploading
  • Memory Processing: Files are processed in your browser's memory and discarded after conversion
