Mastering HTML Encoding for Web Security

HTML encoding is a fundamental security practice used to convert plain text into a format that is safe to display in an HTML document. By converting characters like < and > into &lt; and &gt;, you prevent the browser from interpreting them as actual code, effectively neutralizing Cross-Site Scripting (XSS) threats.

Common HTML Entities

&&amp;
<&lt;
>&gt;
"&quot;
'&#39;
©&copy;
€&euro;
&nbsp;

How to use HTML Entity Encoder

  1. Paste or type your input into the editor on the left.
  2. Leave the defaults, or tweak them if the tool exposes options.
  3. The result appears on the right as you type.
  4. Copy the output or download it.

This tool runs in your browser. Your input is not uploaded or stored.

Use it from the API

Everything this page does is also available as a REST endpoint, so you can call HTML Entity Encoder from your own code, a script or a CI pipeline.

Bash
curl "https://api.toolsxpo.com/v1/html-encode" \
  -H "Authorization: Bearer txp_live_YOUR_KEY"

The endpoint returns a JSON envelope ({ ok, data, meta }) and costs 1 credit per successful call. Try it in the playground or browse the full API reference.
