How to strip comments from code

Strip in 3 steps

Takes ~5 seconds
  1. 1
    Paste your code

    Add the text or source code containing comments into the input box.

  2. 2
    Strip comments

    Click "Strip Comments" to remove all matched comment patterns in one pass.

  3. 3
    Copy the result

    Copy or download the cleaned output with comments removed and structure intact.

This is a pattern-based heuristic, not a full language parser — sequences like // inside string literals may also be stripped. See the FAQ for details.

Who should use this tool?

  • Developers cleaning up code snippets before sharing or minifying
  • Technical writers removing inline comments from documentation examples
  • Analysts stripping annotated config files down to bare values

Examples

Strips a // line comment, leaving the code line intact.

Input
const x = 42; // answer to everything
const y = 7;
Output
const x = 42;
const y = 7;

Removes a multi-line /* block comment */ entirely, collapsing it to nothing.

Input
/* Configure settings
   for production */
const debug = false;
Output

const debug = false;

Strips an HTML comment and a # line comment in the same input.

Input
<!-- page header -->
<h1>Hello</h1>
color = red # default theme
Output

<h1>Hello</h1>
color = red

Remove comments from code or text fast

Strip the four most common comment styles from any pasted text or code in a single left-to-right pass. Useful for cleaning up snippets, config files, templates, and markup before sharing, minifying, or diffing.

This strip comments from code tool removes // line comments, # line comments, /* block comments */, and <!-- HTML comments --> using fast pattern-based matching. Unlike a full language parser, it works on any text format without setup. Block comments spanning multiple lines are collapsed entirely; comment-only lines become empty lines so the surrounding line numbers stay meaningful. Everything runs locally in your browser for instant, private processing.

Four comment styles

Handles the most common comment formats found in code and markup.

  • // line comments
  • # line comments
  • /* block comments */
  • <!-- HTML comments -->
Structure preserved

Line numbers stay meaningful — comment-only lines become empty lines, not deleted lines.

  • Line numbers intact
  • Block comments collapsed
  • Trailing whitespace trimmed
Private by default

All processing runs in your browser. Your code is never uploaded anywhere.

  • No server upload
  • Works offline
  • Instant output
Privacy first: we never send your input to a server. Everything runs locally in your browser.

Tips for best results

Keep the tool's heuristic nature in mind when processing real source files.

  • Avoid running this on code that embeds // or # inside string literals — those will be stripped too, as documented.
  • For config files, double-check that # in values (like color hex codes without a space) aren't accidentally caught.
  • Use a proper language-aware minifier or AST tool when precision matters for production code.

Frequently asked questions

Will // inside a URL like https://example.com be stripped?>
Yes. This tool uses pattern matching, not a language parser, so it cannot tell a // in a string literal apart from a real line comment. The // in a URL will trigger comment stripping for the rest of that line. This is a known limitation, documented clearly.
What happens if a /* block comment is never closed?>
Everything from the opening /* to the end of the input is treated as part of the comment and removed entirely. There is no error — the tool handles it gracefully.
Does stripping a comment delete its line entirely?>
No. A line that becomes empty after its comment is removed stays as an empty line. This keeps line numbers in surrounding code meaningful. Only trailing whitespace on that line is trimmed.
Can a // or # inside a /* block comment */ accidentally trigger line comment stripping?>
No. The tool processes input in a single left-to-right pass, so once a /* block comment */ is matched and consumed, any // or # inside it is already part of the removed content and is not re-processed.
