Frequently Asked Questions

Why remove comments from code?

Removing comments can be useful for creating production builds, reducing file size, sharing clean code examples, focusing on code structure, or preparing for minification. While comments are valuable during development, there are many scenarios where comment-free code is preferred.

Is my code processed securely?

Yes, all processing happens entirely in your browser. Your code is never sent to any server, ensuring complete privacy and security. This tool is safe to use with proprietary or sensitive code bases.

What's the difference between line and block comments?

Line comments typically start with characters like '//' or '#' and continue until the end of the line. Block comments have opening and closing delimiters like '/*' and '*/' and can span multiple lines. Different languages use different symbols for these comment types.

Will this tool preserve string literals that contain comment syntax?

The tool uses regular expressions to identify comments based on language-specific patterns. While it works well for most code, extremely complex cases with comment-like syntax inside string literals may occasionally require manual review.
