It helps clean up source files by removing unnecessary annotations, with options to preserve shebang lines for scripts. ## Inputs - **Code Input** (textarea): Paste your code here... - **Remove Single-Line Comments (//)** (checkbox) - **Remove Multi-Line Comments (/* */)** (checkbox) - **Preserve Shebang (#!)** (checkbox) ## When to use - When you need to remove commented-out code or annotations before deploying to production. - When sharing code snippets and want to eliminate distracting comments. - When debugging to focus on active code without legacy comments. ## How it works - Paste your code into the input textarea. - Select which comment types to remove: single-line, multi-line, or both. - Optionally enable 'Preserve Shebang' to keep #! lines intact. - The 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 - Cleaning up legacy codebases where comments are outdated or redundant.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. ## Frequently asked questions ### What comment styles does this tool remove? It removes single-line comments starting with // and multi-line comments enclosed in /* */. ### Can I choose to remove only one type of comment? Yes, you can toggle the removal of single-line and multi-line comments independently using the checkboxes. ### Does it support other comment formats like HTML or Python? No, it is designed specifically for C-style comments (// and /* */) common in languages like JavaScript, C, and Java. ### Is my code secure when using this tool? The tool processes code client-side in your browser; no data is sent to a server, ensuring privacy. ### What happens to shebang lines? By default, shebang lines (#!) are preserved to maintain script executability, but you can disable this if needed. ## Related tools - [Array Element Deleter](https://elysiatools.com/en/tools/array-element-deleter): Delete specific elements from arrays with support for multiple deletion methods - [BOM Character Remover](https://elysiatools.com/en/tools/data-bom-remover): Remove BOM (Byte Order Mark) characters from text and file content.
