HTML Beautifier

Beautify, validate and minify your HTML code with proper indentation and formatting

What is HTML?

HTML (HyperText Markup Language) is the standard markup language used to create and structure content on the web. It defines elements such as headings, paragraphs, links, images, forms, and more to build webpages.

An HTML document consists of nested elements with tags that tell browsers how to display the content.

Example:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <title>Prettify Code</title>
</head>
<body>
  <h1>Welcome to Prettify Code!</h1>
  <p>I love prettifycode.com!</p>
  <ul>
    <li>Beautify</li>
    <li>Minify</li>
    <li>Validate</li>
  </ul>
</body>
</html>

HTML is the backbone of all web pages and is used alongside CSS and JavaScript to build interactive and visually appealing websites.

What is an HTML Beautifier?

An HTML Beautifier is a tool that formats raw, minified, or poorly structured HTML code into a clean, readable layout with proper indentation, spacing, and line breaks.

Using an HTML beautifier helps you:

  • Read and understand complex or messy HTML easily
  • Spot missing closing tags or syntax errors
  • Share well-formatted HTML with colleagues or clients
  • Improve maintainability of your web projects

If you work with compressed HTML or get snippets from external sources, an HTML beautifier instantly restores clarity.
