How to use the HTML Formatter

This tool is designed to be completely intuitive and runs 100% locally in your browser. None of your HTML code is sent to our servers.

  1. Paste your code: Copy your messy or minified HTML and paste it into the left editor (Input HTML).
  2. Select indentation: Choose your preferred indentation level from the dropdown (2 spaces, 4 spaces, or tabs).
  3. Beautify: Click the primary "Beautify HTML" button or use the keyboard shortcut Ctrl+Enter (or Cmd+Enter on Mac).
  4. Export: Use the Copy or Download buttons in the right editor to get your newly formatted code.

Tool Limitations & Security

The formatter treats your input as purely untrusted text. It parses tags and applies spacing without rendering the code via innerHTML, preventing malicious script execution in your browser environment.

Please note that this is a formatter, not a validator. If your original HTML contains missing closing tags or syntax errors, the formatter will attempt its best to align them, but it cannot automatically inject missing elements.

Quick FAQ

Yes. All processing is done client-side using JavaScript. Your code never leaves your device.
No, HTML Beautifier only adjusts whitespace between block-level tags. The structure and functionality remain identical.
