What is HTML Entity Encoding?

HTML entity encoding converts special characters to HTML entity references, ensuring they display correctly in HTML documents without being interpreted as HTML tags.

Features

  • Two-way conversion: Encode and decode modes
  • Basic encoding: Encodes special characters (<, >, &, ")
  • Full encoding: Converts all characters to numeric entities ({)
  • Entity reference: Common HTML entity lookup table

Common Entities

  • &lt; - Less than (<)
  • &gt; - Greater than (>)
  • &amp; - Ampersand (&)
  • &nbsp; - Non-breaking space
  • &copy; - Copyright (©)

Use Cases

  • XSS Prevention: Encode user input to prevent XSS attacks
  • HTML Escaping: Display HTML code as text
  • Special Symbols: Display copyright, trademark symbols in HTML
