Why Encode HTML?

HTML encoding converts characters that have special meaning in HTML into their entity equivalents. This prevents browsers from interpreting user input as HTML markup, which is essential for preventing XSS (cross-site scripting) attacks and displaying code snippets correctly.

  • Prevent XSS vulnerabilities in web applications.
  • Display HTML source code on web pages.
  • Safely render user-generated content.
  • Prepare text for embedding in HTML attributes.
