Frequently Asked Questions
What does an HTML Beautifier do?
It takes minified or poorly formatted HTML and restructures it with proper indentation and line breaks, making it easy to read, maintain, and debug.
Does it fix invalid HTML?
The beautifier formats your HTML as-is without rewriting invalid tags. For validation, use an HTML validator tool alongside it.
Is this safe to use for private code?
Yes — all processing is done entirely in your browser using JavaScript. Nothing is uploaded to any server.
Can I use it to format HTML inside JSX?
For JSX-specific formatting, use our HTML to JSX converter. This tool is optimized for standard HTML5 markup.
