Code Formatter & Minifier
Beautify or minify JSON, JavaScript, CSS, HTML, XML and SQL — all in your browser.
How to Use Code Formatter
To format (beautify) code, paste your JavaScript, CSS, or HTML into the input area and click Beautify. The tool applies consistent indentation, spacing, and line breaks to produce clean, readable code. Select the language from the dropdown to ensure the correct formatting rules are applied.
Click Minify to remove all unnecessary whitespace and produce the most compact version of the code for production use. The stats panel shows the size before and after. This tool is useful for cleaning up minified code for debugging, standardising code style, and preparing code for production deployment.
Frequently Asked Questions
What languages does the code formatter support? expand_more
The formatter supports JavaScript (JS), CSS, and HTML. Each language uses appropriate formatting rules and indentation conventions.
What is the difference between formatting and minifying? expand_more
Formatting (beautifying) adds whitespace, line breaks, and indentation to make code human-readable. Minifying removes all that extra whitespace to produce the smallest possible file for faster loading.
Can I use this to unminify third-party code? expand_more
Yes. Paste minified JavaScript, CSS, or HTML into the input and click Beautify to expand it into a readable form for inspection and debugging.
Does formatting change how the code runs? expand_more
No. Formatting only changes whitespace and presentation. The logic, syntax, and execution behaviour of the code remain identical after formatting.
What indentation size does the formatter use? expand_more
The formatter defaults to 2-space indentation for JavaScript and 4-space for some other conventions. The output follows commonly accepted style conventions for each language.
