How to Format HTML - Step by Step Guide

Step 1

Input Your HTML Code

Let's get your HTML into the formatter! You have several convenient options:

•
Paste directly: Copy your HTML code from your editor or web page source and paste it into the input editor
•
Upload a file: Click "Upload" to select a .html, .htm, or .txt file from your computer
•
Try the sample: Click "Sample" to load example HTML and see how the formatter works 😊

Example: Unformatted HTML Input

Here's what messy, unformatted HTML looks like:

<div class="container"><h1>Welcome</h1><p>This is a sample paragraph with some content.</p><ul><li>First item</li><li>Second item</li></ul></div>
Step 2

Automatic Formatting & Validation

The magic happens instantly! 🎉 As soon as you input HTML, the formatter automatically:

•
Validates structure: Checks for errors and highlights issues with helpful suggestions
•
Adds proper indentation: Makes nested elements and HTML tags easy to read
•
Syntax highlighting: Color-codes different HTML elements for better readability

  <p>This is a sample paragraph with some content.</p>
  <ul>
    <li>First item</li>
    <li>Second item</li>
  </ul>
</div>
Step 3

Choose Format Options

Customize your output based on your needs! 🎛️ The formatter gives you control over how your HTML appears:

•
Pretty format: Default beautified HTML with proper indentation (2 spaces)
•
Minify option: Click "Minify" to compress HTML into minimal whitespace for production use
•
Syntax highlighting: Color-coded elements make it easy to spot different HTML tags and attributes
Step 4
