How Your Privacy is Protected

1

Files Stay Local

When you select images, they're read directly into your browser's memory. They never touch a server.

2

Browser Does the Work

Conversion uses the HTML5 Canvas API built into your browser. All processing happens on your CPU.

3

Direct Download

Converted files are generated in memory and downloaded directly to your device. No cloud storage involved.

Don't just trust our word—inspect the source code yourself. Built with vanilla JavaScript for maximum transparency.
