Beautify and format HTML code instantly with our free online HTML beautifier. This tool helps web developers transform minified HTML into readable, properly indented format for easier editing and debugging. Simply paste your HTML and get beautifully formatted output in real-time.
HTML Beautifier formats your HTML code with proper indentation, line breaks, and spacing, making it more readable and maintainable. Perfect for cleaning up minified or poorly formatted HTML.
HTML beautifier formats and indents HTML code for readability. Transforms minified or poorly formatted markup into clean, consistently indented code. Essential for code review, debugging, learning HTML structure, and maintaining readable templates.
The beautifier parses HTML into a DOM tree, then serializes it back with consistent indentation. Block elements get newlines and indentation. Inline elements stay on same line. Attributes can be formatted one per line for complex elements. Preserves content but restructures whitespace.
Uses HTML5 parsing rules tolerant of malformed markup. Void elements (br, img, input) handled correctly without closing tags. Script/style content preserved as-is. Options: indent size (2/4 spaces or tabs), max line length, attribute wrapping threshold, preserve inline elements setting.

<!-- Before (minified) -->
<div class="container"><header><nav><ul><li><a href="/">Home</a></li><li><a href="/about">About</a></li></ul></nav></header><main><article><h1>Title</h1><p>Content</p></article></main></div>
<!-- After (beautified) -->
<div class="container">
<header>
<nav>
<ul>
<li><a href="/">Home</a></li>
<li><a href="/about">About</a></li>
</ul>
</nav>
</header>
<main>
<article>
<h1>Title</h1>
<p>Content</p>
</article>
</main>
</div>Each block element gets proper indentation showing nesting. Inline elements (a, li content) stay together.
Use HTML beautifier for development, code review, debugging, and documentation. Use minified HTML for production to reduce file size.
Usually no. Beautifying only changes whitespace, which browsers mostly ignore in HTML. Exception: pre/code elements where whitespace matters, and inline elements where added whitespace can create text spacing.
