How do I convert a JS file to TSX?

Visit the JS to TSX converter, upload your .js file, and select TSX as the output. The tool analyzes your JavaScript, detects React components, and generates a .tsx file with inferred TypeScript types for props, state, and event handlers. Finally, download the .tsx file and add it to your React project.

Why should I convert JavaScript to TSX?

TSX is the standard format for React components written in TypeScript. It adds compile-time type checking, which catches errors before runtime, improves IDE autocomplete and refactoring safety. Converting to TSX makes your codebase more maintainable and scalable, especially for large teams.

How does the converter handle existing type annotations and comments?

The converter preserves JSDoc comments and uses them as hints for type inference. It also keeps all runtime logic intact—including arrow functions, hooks, and async operations—while adding explicit interfaces for props and state. If a type cannot be inferred, it defaults to a safe fallback like `any` with a TODO comment for manual tuning.

Is JS-TO-TSX free to use?

Yes, JS-TO-TSX on LetsConvert is 100% free with no registration or hidden fees required.

Does this converter work on mobile phones and tablets?

Yes! JS-TO-TSX works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
