When to Use This Tool
Remove comments before minifying or obfuscating code for production deployment. Eliminate explanatory text that reveals implementation details while keeping the code functional.
Recommended: Production builds
Extract pure code examples for documentation or tutorials. Remove explanatory comments to show only the essential code structure, making examples cleaner and more focused.
Recommended: Documentation
Strip comments to get accurate lines-of-code metrics for codebase analysis. Measure actual code volume without commentary, useful for project estimation and complexity analysis.

Frequently Asked Questions
Which programming languages are supported?
This tool supports 15+ languages including JavaScript, TypeScript, Python, Java, C, C++, C#, Go, Swift, PHP, Ruby, HTML, CSS, SQL, and more. It automatically detects and handles language-specific comment syntax.
Will this break my code?
No! The tool uses smart parsing to only remove actual comments, not comment-like syntax in strings, URLs, regex patterns, or division operators. Your code structure and functionality remain completely intact.
What about comments inside strings?
The strip-comments library intelligently handles edge cases. Comments within string literals, regex patterns, or URLs are preserved. Only actual code comments are removed, ensuring your code works correctly.
Is my code kept private?
Absolutely! All comment removal happens entirely in your browser using client-side JavaScript. Your code is never sent to any server, ensuring complete privacy and security for your sensitive code.
Can I keep license headers?
Yes! Enable the 'Preserve protected comments' option to keep comments starting with /*! which are commonly used for copyright notices, license headers, and important legal text.
