What is a Comment Remover?
A Comment Remover (or comment stripper) is a tool that removes comments from source code without affecting the executable code. Comments are human-readable annotations that are ignored by compilers and interpreters — removing them reduces file size and can make the code cleaner for production deployment.
This tool supports multiple programming languages and comment syntaxes, including single-line comments (//, #, --), multi-line comments (/* */, <!-- -->), and documentation strings (Python docstrings). All processing is done safely — comments inside string literals are preserved.
How to Use
- Paste your source code into the input textarea.
- Select the programming language (or use Auto-detect).
- Choose comment types to remove: single-line, multi-line, and/or docstrings.
- Click "Remove Comments" to strip all matching comments.
- Copy the cleaned code or Download as a file.
Frequently Asked Questions
Will removing comments break my code?
No. Comments are ignored by compilers and interpreters — they exist only for humans. The tool carefully preserves string literals so that comment-like patterns inside strings (e.g. "http://example.com") are not affected.
Is my code stored on a server?
No. All processing happens entirely in your browser using JavaScript. Your code never leaves your device.
Why "Auto-detect" language?
Different languages use different comment syntaxes. Auto-detect examines your code and selects the most likely language based on file extension hints, keywords, and comment patterns. For best results, select the language manually.
What are docstrings?
Docstrings are multi-line string literals used as documentation in Python ("""...""" or '''...'''). Unlike regular comments, docstrings are actual string values that can be accessed at runtime. Removing them is optional and disabled by default.
