HTML Entities Encoder Online

The HTML Entities Encoder Online is a free browser-based tool that converts special characters, symbols, and Unicode text into HTML entities. HTML entities help display reserved characters correctly in web pages while preventing them from being interpreted as HTML markup.

Whether you're developing websites, writing HTML code, creating email templates, or preparing user-generated content, this tool makes it easy to safely encode text into HTML entities without installing any software.

What Are HTML Entities?

HTML entities are special codes used to represent reserved characters and symbols in HTML documents. Instead of displaying characters like <, >, or & directly, HTML uses entity references such as &lt;, &gt;, and &amp;.

HTML entities ensure that browsers correctly display special characters instead of interpreting them as HTML tags or markup.
