Free Online HTML Beautifier & Minifier
This tool formats messy or minified HTML code with proper indentation and line breaks, making it easy to read and edit. It also includes a minification mode that removes all unnecessary whitespace, comments, and line breaks to produce the smallest possible HTML for production use. Everything runs in your browser — no data is sent to any server.
Beautify Mode
The beautifier parses your HTML and adds proper indentation based on tag nesting level. It handles self-closing tags, inline elements, void elements (like img, br, input), script and style blocks, and HTML comments. Choose between 2-space, 4-space, or tab indentation to match your coding style.
Minify Mode
The minifier removes unnecessary whitespace between tags, collapses multiple spaces into one, removes HTML comments, and strips blank lines. This reduces file size for faster page loading. Whitespace inside pre and code tags is preserved to maintain formatting of code blocks.
Frequently Asked Questions
Yes. Content inside script and style tags is preserved as-is during beautification. The tool focuses on HTML structure formatting and doesn't modify embedded code.
Typical HTML files see a 10-30% size reduction from minification, depending on how much whitespace and comments the original contains. Files with heavy indentation see the largest savings.
This tool formats existing HTML but doesn't repair broken markup. Missing closing tags, malformed attributes, or invalid nesting won't be corrected — use an HTML validator for that.
