HTML Entity Encoder/Decoder: a worked example

You need to show a literal code snippet containing tags and quotes inside an HTML page without it being parsed as markup.

Raw text

<script>alert("Tom & Jerry")</script>
HTML Entity Encoder/Decoder produces

Entity-encoded

&lt;script&gt;alert(&quot;Tom &amp; Jerry&quot;)&lt;/script&gt;

The five characters that break (or exploit) HTML, `< > & " '`, are replaced with their named entities so the browser renders them as text instead of executing or mis-parsing them. This is the exact transformation that prevents reflected XSS when untrusted text lands in markup; the tool also decodes in the other direction.

What is HTML Entity Encoder/Decoder?

Encode special characters into HTML entities or decode entities back to readable text. Handles named entities (&amp;), numeric (&#38;), and hex (&#x26;) formats.

How to use

  1. 1Paste text or HTML into the input.
  2. 2Choose encode or decode mode.
  3. 3Copy the result.

Frequently asked questions

When do I need to encode HTML entities?

Whenever you're inserting user-provided text into an HTML page. Encoding prevents XSS attacks and rendering issues from characters like <, >, and &.

What's the difference between named and numeric entities?

Named entities like &amp; are easier to read. Numeric entities like &#38; work for any Unicode character, including those without a named form.
