What this tool does

Convert characters to HTML entities or decode entity references back to text. Named, decimal, hexadecimal, and minimal-safe modes are supported, and decoded output is displayed as text rather than executed as HTML.

How to use it

  1. Enter or import the content you want to process.
  2. Choose the required options and run the tool.
  3. Review the output and limitations, then copy or download it.

Capabilities and limitations

Strict decoding reports malformed references; forgiving mode follows the selected library behavior. Decoded text is never inserted as executable HTML.
