How Local Processing Works

1

Selected in Browser Memory

When you select or drop a file, your browser creates a temporary local Blob / ArrayBuffer pointer directly in your device's RAM.

2

Processed Client-Side

Our client-side engine (HTML5 Canvas & Client JavaScript) processes the data directly using your computer or phone's CPU.

3

Saved Directly to Your Downloads

The resulting output is downloaded immediately to your device. When you close or refresh the tab, memory is cleared automatically.

Verify It Yourself

Open your browser's Developer Tools (F12 or Ctrl+Shift+I), switch to the Network tab, and convert any file. You will see zero network POST requests carrying file data.
