TypeScript to JavaScript Converter
Strip TypeScript types — annotations, interfaces, generics, enums — into runnable JavaScript.
Strips type annotations, interfaces, type aliases, generics, as/satisfies assertions, access modifiers, type-only imports, and converts enums to const objects. Strings, comments and regexes are preserved. It is a fast eraser, not a full compiler — review the output for unusual type expressions.
About this tool
Remove TypeScript types online: annotations, interfaces, type aliases, generics, enums, and as-assertions become clean JavaScript. Free and client-side. TypeScript to JavaScript Converter runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- TypeScript to JavaScript Converter is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
