An HTML formatter takes minified, pasted, or inconsistently indented HTML and restructures it with clean indentation and line breaks. Unlike general-purpose formatters, this tool understands HTML-specific rules: void elements, inline vs. block elements, attribute ordering, and proper tag nesting — giving you full control over how your markup is presented.

How to Format HTML Code
Minified HTML saves bandwidth in production but makes development painful. An HTML formatter restores readability by adding proper indentation and line breaks while preserving semantic meaning. Whether you received compressed HTML from a CMS, legacy system, or API, this tool restructures it instantly.
Step 1: Paste Your HTML
Copy the HTML you want to format — minified page source, a code snippet, a template fragment, or an entire document — and paste it into the input textarea. The tool accepts any HTML, including HTML5 documents with DOCTYPE declarations and inline scripts or styles.
Step 2: Choose Format Options
Select your preferred indent style (spaces or tabs) and size (2 or 4 for spaces). Optionally enable
Sort Attributes to alphabetize tag attributes for consistent style, or
Self-close void elements to add />
to tags like <br> and
<img> for XHTML compatibility.
Step 3: Format or Minify
Click Format HTML to produce a beautified, indented result. Click Minify to collapse the HTML into a compact single-line version by removing all non-essential whitespace. Both operations respect HTML void elements — tags that cannot have children — and handle them correctly without extra indentation.
Step 4: Copy or Download
Use Copy to put the output on your clipboard, or Download to save it
as an .html file. Everything processes
locally in your browser — no server uploads, no data retention.
FAQ
Is this HTML formatter free?
Yes, completely free with no limits, no account required, and no usage caps. Format as much HTML as you need.
Is my HTML code safe when I use this tool?
Yes. All formatting happens entirely in your browser. Your code is never sent to any server, never stored, and never logged. It is safe to use with private or proprietary code.
What is the difference between this and a general code formatter?
This formatter is HTML-specific: it understands inline vs. block elements, void elements (br, hr, img, input, etc.), and HTML attributes. General formatters like Prettier are great for most uses, but this tool gives you fine-grained control over HTML-specific formatting options.
What does Sort Attributes do?
When enabled, attributes within each HTML tag are sorted alphabetically. For example, <div id='a' class='b'> becomes <div class='b' id='a'>. This is useful for normalizing attribute order across large codebases.
What are void elements and how are they handled?
Void elements are HTML tags that cannot have child content and do not need a closing tag: br, hr, img, input, link, meta, area, base, col, embed, param, source, track, and wbr. The formatter does not add indentation inside void elements.
Can I choose tabs instead of spaces?
Yes. Use the Indent Style option to switch between spaces and tabs, and the Indent Size option to choose 2 or 4 spaces when using spaces.
Does the formatter handle minified HTML?
Yes. You can paste minified or unformatted HTML and the formatter will restructure it with proper indentation and line breaks, making it readable again.
How do I minify HTML to save space?
Click the Minify button to collapse your HTML into the most compact form by removing all unnecessary whitespace and newlines.
