Frequently Asked Questions
What does TypeScript to JavaScript conversion do?
It strips all TypeScript-specific syntax: type annotations, interfaces, type aliases, generic parameters, access modifiers (public/private/protected/readonly), and non-null assertions (!). The logic and variable names stay identical — the output is clean JavaScript that runs without a TypeScript compiler.
When would I need to convert TypeScript to JavaScript?
Common reasons: using TS code in an environment that doesn't support TypeScript, sharing a snippet with a JS-only project, quickly previewing the compiled output without running tsc, or migrating away from TypeScript.
Is the output equivalent to tsc --noEmit output?
For most code, yes. The AI removes the same type-only constructs that the TypeScript compiler erases. Complex type-only imports (import type) are also removed.
Is the tool free?
Yes, completely free with no account required.
Does JS2TS store my code?
No. Conversions are processed in real time and never stored on our servers.
