How do I escape HTML in text?

  2. Paste the raw text (for example a snippet with < and &).
  3. Read the escaped output and click Copy.

Encode always writes &amp;, &lt;, &gt;, and &quot; for the four markup characters. Turn on non-ASCII to also emit &#…; codes for accented letters.

How do I decode HTML entities?

  1. Switch to Decode.

Decode accepts decimal &#160; and hex &#xA0; forms, plus common named entities such as &nbsp; and &copy;.

HTML entities vs URL encode

HTML entities escape markup characters for HTML or XML. URL encode (percent-encoding) escapes query values for a URL. GustKit has both tools; pick the one that matches your output.
