Code Comment Remover
Remove comments from JavaScript, Python, CSS, HTML, PHP, Java and C++ code in one click. Clean up source code for production and shrink file size. Free and private.
About this tool
Strip every comment out of JavaScript, Python, CSS, HTML, and other source files, leaving only executable code — with each language's comment syntax handled correctly, including the tricky cases. Developers clean files before publishing, sharing externally, or measuring what a codebase actually contains.
How to Remove Code Comments
- 1
Paste your source code and indicate its language, so the right comment syntax rules apply — // and /* */ for JavaScript, # for Python, <!-- --> for HTML, and so on.
- 2
Run the removal: single-line comments, block comments, and inline trailing comments are all stripped while code lines are preserved untouched.
- 3
Copy the comment-free code for deployment, sharing, or analysis.
Why Strip Comments with Wrklyst
- Source Never Leaves Your Tab
- Comment stripping is local text processing — a serious consideration, since internal comments are often the most sensitive part of a file.
- Language-Aware Accuracy
- A URL's // isn't a comment and a # inside a Python string isn't either; syntax-aware removal avoids the corruption naive find-and-delete causes.
- Whole Files in One Pass
- Thousands of lines process instantly — no manual scrolling hunt for every stray annotation.
Comment Hygiene Tips
- Strip a copy, keep the original — comments are for maintenance, and you're the maintainer.
- Audit what got removed before sharing externally; the diff shows exactly what outsiders would have seen.
- Preserve license headers when a library's terms require attribution.
- Comparing two files' logic? Strip comments from both first so the diff shows only code.
Frequently asked questions
Why remove comments before sharing code?
Comments accumulate things outsiders shouldn't see: internal ticket references, colleague names, frank TODO admissions, commented-out old approaches, and occasionally credentials. Stripping them before sending code to clients, publishing examples, or posting snippets is basic hygiene — the code speaks, the internal monologue doesn't.
Will removal ever break my code?
Language-aware parsing protects the dangerous cases — string literals containing comment-like sequences stay intact. The one genuine caveat: some tools treat special comments as directives (linter pragmas like eslint-disable, TypeScript triple-slash references, 'use strict' is a string not a comment). Review the output if your file relies on directive comments.
Does removing comments make code faster or smaller?
Smaller on the wire, yes — comments are dead weight in shipped JavaScript or CSS, and stripping them cuts bytes. Faster, no: interpreters and compilers skip comments at parse time. For production web assets, a full minifier does this plus whitespace and renaming; this tool is the surgical, comments-only version.
Can I remove comments from minified or third-party code?
Yes — a common case is trimming the license-banner-riddled output of bundlers, though note some licenses require preserving attribution comments; check before stripping legally significant headers. For readable third-party code, removing comments before a rewrite gives you a clean baseline to annotate in your own words.
