About HTML Encoding and Decoding

HTML encoding is essential for web security and proper content display. It converts special characters like <, >, and & into HTML entities to prevent XSS attacks and ensure your content displays correctly in web browsers.

When to Use HTML Encoding

  • Displaying user input safely on web pages
  • Showing HTML code examples in tutorials
  • Preventing XSS (Cross-Site Scripting) attacks
  • Ensuring proper character display across browsers
  • Processing form data and user comments

Common HTML Entities

  • &lt; - Less than symbol (<)
  • &gt; - Greater than symbol (>)
  • &amp; - Ampersand symbol (&)
  • &quot; - Double quote (")
  • &#39; - Single quote (')

Security Benefits

HTML encoding is crucial for preventing XSS attacks. When user input contains malicious scripts, encoding converts them into harmless text that browsers display safely instead of executing as code. This protects your website and users from security vulnerabilities.
