HTML Formatter / Beautifier

Format, beautify and minify HTML code.

How to Use the HTML Formatter

Paste your HTML into the input box, then click "Format" to beautify it with proper indentation, or "Minify" to compress it into a single line. Choose between 2-space, 4-space or tab indentation.

What This Tool Does

  • Format/Beautify — adds indentation and line breaks for readability
  • Minify — removes comments, collapses whitespace and compresses HTML
  • Indent Options — choose 2 spaces, 4 spaces or tabs

The tool handles self-closing tags, void elements (like <br>, <img>, <input>), comments, and DOCTYPE declarations. All processing runs entirely in your browser — no data is sent to any server.

Frequently Asked Questions

Does this tool validate HTML?

This tool formats HTML but does not validate it. It will indent tags and add line breaks regardless of whether the HTML is technically valid.

How does it handle self-closing tags?

Void elements like <br>, <img>, <hr> and <input> are recognized automatically and do not increase indentation. Tags ending with /> are also treated as self-closing.

What does Minify do?

Minify removes HTML comments, collapses all whitespace between tags, and reduces the HTML to the smallest possible output.

Is there a size limit?

There is no hard limit, but very large HTML documents may be slow to process in the browser.

Does my HTML get uploaded?

No. All formatting happens locally in your browser. Your data never leaves your device.
