Is my source code uploaded to a server?

No. Conversion runs entirely in your browser with JavaScript. Your code never leaves your device.

How accurate is automatic code conversion?

Popular pairs (Python, JavaScript, Java, Go, C#, etc.) use dedicated rewrite rules. Other pairs may use a JavaScript pivot or annotated passthrough — always review before production use.

Can I convert entire projects?

This tool is optimized for snippets, homework samples, and algorithm ports. Multi-file projects need manual structure and import adjustments.
