About HTML Entities Encoder & Decoder

What are HTML Entities?

HTML entities are character sequences used to represent characters that have special meanings in HTML or are outside the standard ASCII character set. For example, characters like < and > must be encoded as &lt; and &gt; respectively to prevent browsers from parsing them as HTML tags.

Using an encoder/decoder ensures code safety (preventing Cross-Site Scripting or XSS vulnerabilities) and preserves accurate character representations across all platforms and databases.

Key Encoding Features:

  1. Named Entities: Replaces characters with intuitive names defined by the HTML spec (e.g., &copy; for ©).
  2. Decimal Entities: Formats characters as their decimal code point values (e.g., &#169;).
  3. Hexadecimal Entities: Formats characters as their hex code point values (e.g., &#xa9;).

This tool runs entirely in your browser using local JavaScript, ensuring zero risk of server-side data snooping.
