How do I convert a TypeScript file to JavaScript using your tool?

Simply paste or upload your .ts file, choose the target ECMAScript version (e.g., ES5, ES6, ES2020), and click 'Convert'. The tool strips type definitions and outputs a .js file you can download or copy.

Why convert TypeScript to JavaScript instead of using TypeScript directly?

Browsers and many JavaScript runtimes only understand plain JavaScript. Converting TS to JS removes type annotations and interfaces, eliminating the need for a build step in production. It also ensures compatibility with tools that lack TypeScript support.

What happens to TypeScript-specific features like interfaces, generics, and access modifiers during conversion?

Interfaces, type aliases, and generics are entirely erased since they exist only at compile-time. Access modifiers like public/private are also stripped. You can select an ECMAScript target to transpile syntax like async/await or arrow functions into older JavaScript versions if needed.

Is TS-TO-JS free to use?

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

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! TS-TO-JS 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.
