# HTML Formatter & Beautifier

Format, indent, and prettify messy HTML markup with configurable indentation rules and tag preservation.

## What is HTML Formatter & Beautifier?

The HTML Formatter re-indents HTML so the nesting of elements is easy to read. Paste minified or messy markup — from a CMS, email builder or browser DevTools — and get consistently indented code with each block element on its own line. Choose 2 spaces, 4 spaces or tabs. Formatting only changes whitespace between tags, so the rendered page looks the same.

## How to use HTML Formatter & Beautifier

1. **Paste HTML** — Paste the markup or load the sample.
2. **Choose indentation** — Select 2 spaces, 4 spaces or tabs.
3. **Copy the formatted HTML** — The beautified code appears instantly, ready to copy.

## Frequently asked questions

### Will formatting change how my page looks?

Normally no. Only whitespace between tags changes; content inside <pre> and <textarea> is left alone.

### Does it fix invalid HTML?

It re-indents what you give it but does not repair missing closing tags. Unbalanced tags will show up as odd indentation.

### Can it format inline CSS and JavaScript?

Yes. Embedded <style> and <script> blocks are indented as well.
