1Paste your code into the input textarea.
2Select which comment types to remove: single-line, multi-line, or both.
3Optionally enable 'Preserve Shebang' to keep #! lines intact.
4The tool processes the code and outputs a clean version without the specified comments.

Use cases

Minifying JavaScript files by removing comments to reduce file size.
Cleaning up legacy codebases where comments are outdated or redundant.
Preparing code for academic submissions where comments might be considered distractions.

Examples

1. Clean JavaScript for Production

Web Developer

Background

A developer is finalizing a JavaScript module for deployment and wants to remove all comments to reduce bundle size.

Problem

The code has numerous single-line and multi-line comments that are not needed in production.

How to use

Paste the JavaScript code into the input, ensure both 'Remove Single-Line Comments' and 'Remove Multi-Line Comments' are checked, and keep 'Preserve Shebang' enabled if applicable.

Outcome

The output is clean JavaScript code without any // or /* */ comments, ready for minification and deployment.

How to use

Upload or paste the C code, select to remove both comment types, and preserve shebang if it's a script.

Outcome

The code is output without comments, making it easier to focus on the logic during review.
