HTML Formatter
Format and beautify HTML code
Frequently Asked Questions
How does the HTML Formatter work?
Paste minified or messy HTML and the formatter adds proper indentation, line breaks, and consistent spacing. It handles nested elements, self-closing tags, and preserves content within pre and code blocks.
Can I minify HTML with this tool?
Yes. Switch to minify mode to remove unnecessary whitespace, comments, and optional closing tags. This reduces HTML file size for production. A typical page saves 10-30% file size after minification.
Does the formatter validate HTML?
The formatter focuses on formatting, not validation. However, it highlights obvious issues like unclosed tags and mismatched nesting. For full HTML validation, use the W3C Markup Validation Service.
Can I format HTML with embedded CSS and JavaScript?
Yes. The formatter recognizes style and script blocks and formats them with appropriate indentation. CSS within style tags and JavaScript within script tags are formatted according to their respective conventions.
What indentation options are available?
Choose 2 spaces, 4 spaces, or tabs for indentation. Set maximum line length for attribute wrapping. Configure whether to put each attribute on a new line for elements with many attributes. Settings are saved for future use.
