Before and after

Real-world TypeScript code on the left. The same code with every comment removed on the right.

typescript-input.ts
// API client for the orders service
import type { Order, OrderStatus } from "./types";

/**
 * Fetch a single order by ID.
 * Throws if the order doesn't exist.
 */
export async function getOrder(id: string): Promise<Order> {
  // Validate UUID format
  if (!isUuid(id)) throw new TypeError("Invalid id");

  const res = await fetch(`/api/orders/${id}`); // GET request
  if (!res.ok) throw new Error("Not found");
  return res.json() as Promise<Order>; // assume server returns Order
}

const ALLOWED: OrderStatus[] = ["pending", "shipped"]; // status filter
typescript-output.tscleaned
import type { Order, OrderStatus } from "./types";

export async function getOrder(id: string): Promise<Order> {
  if (!isUuid(id)) throw new TypeError("Invalid id");

  const res = await fetch(`/api/orders/${id}`);
  if (!res.ok) throw new Error("Not found");
  return res.json() as Promise<Order>;
}

const ALLOWED: OrderStatus[] = ["pending", "shipped"];
Why use it

Built for TypeScript specifically.

TypeScript projects accumulate type-level comments, JSDoc blocks, and inline TODOs that are useful while writing but noisy when sharing snippets, generating compact bundles, or auditing diffs. Uncommenter keeps your type annotations and decorators intact while cleanly removing every flavor of comment, including TSDoc-style /** ... */ blocks if you want them gone.

  • // line and /* */ block comments removed
  • TSX support, including {/* */} inside JSX expressions
  • Type annotations, decorators, and template literals preserved
  • Auto-detection from .ts, .tsx, .mts, .cts extensions
  • Optional preservation of TSDoc / JSDoc blocks
How it works

Strip comments in 30 seconds.

  1. 1

    Open the tool

    Head to uncommenter.com/tool. Nothing to install. Nothing to sign up for.

  2. 2

    Paste your TypeScript code

    Drop your .ts file in, or paste code into the editor. Auto-detection picks up TypeScript from the extension or file content.

  3. 3

    Click 'Remove Comments'

    The parser walks every character with a real state machine, strings, regex, and other context-sensitive parts are detected and left alone.

  4. 4

    Copy or download

    Grab the cleaned output. Your code never left your browser.

FAQ

TypeScript questions, answered.

Does it understand TypeScript-only syntax?

+

Yes. Type aliases, interfaces, generics, decorators, and `as` casts are all preserved exactly as written, the parser only removes comment ranges, never type information.

Will it strip TSDoc blocks too?

+

By default the tool keeps docstring-style /** ... */ blocks. Disable the 'preserve docstrings' option to remove them.

Can I run it as part of a build?

+

Yes. Install the open-source `uncommenter` npm package and use the CLI: `uncommenter src/ -r -g "*.ts"`. See the API & CLI docs for flags.
