About JS2TS

What is JS2TS?

JS2TS is a free developer toolkit that uses AI to convert JavaScript to TypeScript — and much more. Beyond the core JS→TS converter, the site includes 22+ tools covering JSON-to-TypeScript, CSS-to-Tailwind, HTML-to-JSX, YAML-to-JSON, Zod schema generators, and TypeScript reference guides.

Every tool on JS2TS is free, requires no account, and processes code in real time. Your code is never stored on our servers.

Who Builds JS2TS?

JS2TS is built and maintained by 011BQ, a software development agency founded by Shashank Jain. The team builds developer tools, SaaS products, and web applications for clients and as standalone products.

JS2TS started as an internal tool to speed up TypeScript migrations on client projects. After seeing how useful it was, the team open-sourced the concept as a free public tool.
