🔒 Zero-upload workflow: processing is performed locally by JavaScript in your browser. This page does not intentionally upload your source code to a server.

Prepare smaller code excerpts

Select the comment style that matches your source. Use the JavaScript/C-style mode for JavaScript and the hash mode for Python. Copy only after reviewing the result against the original.

Example: const label = "https://example.com"; // explanation keeps the URL string while removing the trailing comment. Multiline string content is preserved during whitespace cleanup.

This is a prompt-preparation helper, not a production compiler. JavaScript comments use a syntax parser when possible; other languages use a conservative scanner. Mixed styles, preprocessor directives, JSX and language-specific literals need manual review. Removing docstrings changes runtime metadata. Do not replace production source with the output without its normal tests.

Code Comment Remover: common questions

How can I remove comments without deleting strings?

Choose the appropriate language mode and inspect the result. Claupt uses a JavaScript parser when possible and conservative scanning for other supported comment styles. Comment-like text inside strings should remain part of the code.

Should I remove every comment before asking AI about code?

No. Keep comments that explain requirements, security assumptions, or non-obvious behavior needed for your question. Remove only material that does not contribute to the task.

Is this a production code minifier?

Claupt prepares code excerpts for prompts. It is not a compiler or a replacement for a language-specific build tool. Review language-specific syntax and run your normal tests before changing production code.
