Does the conversion preserve the original logic and functionality of the TypeScript code?

Yes, the tool strips type annotations while retaining the underlying JavaScript logic, ensuring the output runs in standard runtime environments without altering the core functionality.

Can I convert enums to plain objects instead of runtime enum structures?

The tool offers an option to convert enums to objects; regular enums become object lookups while const enums are inlined as literal constants at compile time.

What happens to type-only imports when converting TypeScript to JavaScript?

Type-only imports (import type { Foo }) are removed during compilation, which may break side effects if the imported values have runtime impact.

Is the conversion processed on the server or in the browser?

All processing occurs in the user's browser; no data is sent to a server, ensuring code privacy and instant conversion.

Is it right for you

Best for

Developers who need to quickly transpile TypeScript code for legacy projects, prototype without a full build pipeline, or verify how typed code behaves when stripped of type annotations.

Limitations

Conversion strips all TypeScript-specific syntax, losing type safety and compile-time checks
Regular enums compile to runtime objects with reverse mappings, which may differ from intended behavior
Type-only imports are removed and may break side effects if not handled carefully
