About HTML Formatter

The HTML Formatter is a free, in-browser tool that instantly beautifies or minifies HTML markup. Poorly indented HTML — whether generated by a CMS, exported from a design tool, or copy-pasted from a webpage — can be extremely difficult to read and maintain. The beautifier walks your document's tag structure and adds correct, consistent indentation so each nested element is visually offset from its parent, making the document hierarchy immediately clear. Void elements like <br>, <img>, <input>, and <meta> are handled automatically and never given a closing tag or incremented indent level. The minifier does the opposite: it collapses all whitespace between tags and trims excess spaces, producing a compact single-line output that loads faster in browsers. Choosing between 2-space and 4-space indentation lets you match your team's coding standards. Because the entire process runs in your browser, your HTML source code — which may include private API responses, internal application markup, or sensitive form structures — is never transmitted to any external server.

How to Use HTML Formatter

  1. Paste your HTML markup into the left input panel.
  2. Select the indentation size (2 or 4 spaces) from the dropdown at the bottom.
  3. Click "Beautify" to add indentation and structure, or "Minify" to compress the HTML into one line.
  4. Inspect the formatted output in the right panel.
  5. Click "Copy" to copy the result to your clipboard, ready to paste into your project.

Frequently Asked Questions

Does this tool handle void/self-closing HTML elements correctly?

Yes. Elements like <br>, <img>, <input>, <hr>, <meta>, and <link> are recognized as void elements and are never given a closing indent or expected closing tag.

Can I format HTML fragments, or does it need to be a full document?

You can format any HTML — full documents with <!DOCTYPE>, partial fragments, or even individual component templates. The tool works on whatever you paste in.

Is this safe for HTML containing sensitive data?

Yes. The formatter runs entirely in your browser. Your HTML is never sent to a server or stored anywhere outside your device.

Will minification break inline scripts or styles?

Inline <script> and <style> blocks may have their internal whitespace collapsed. For robust production minification with script-aware parsing, use a dedicated build tool like HTMLMinifier-terser.

What is the benefit of minifying HTML?

Minified HTML reduces the number of bytes the browser must download, which speeds up page load times — especially on slow connections. It also makes it slightly harder for competitors to read your source markup.
