Why use HTML Entity Encoder?

  • Supports both encode and decode modes with a single toggle.
  • Handles all standard named entities (like &amp; &lt;) plus numeric character references (like &#169;).
  • Prevents XSS vulnerabilities by properly encoding user-generated content for HTML embedding.
  • Runs entirely in your browser — no text is sent to any server.

Common use cases

  • Encode special characters in text before embedding it in HTML to prevent rendering issues and XSS.
  • Decode HTML entities from scraped web content to get the original readable text.
  • Prepare text for CMS fields or email templates where raw HTML characters would break the markup.
  • Convert copyright symbols, trademarks, and special characters to their entity references for HTML.

About HTML Entity Encoder

HTML entities are the mechanism for safely representing special characters like ampersands, angle brackets, and quotes inside HTML markup. Without proper encoding, these characters can break page rendering or introduce XSS security vulnerabilities. Xevon Tools' HTML Entity Encoder handles both directions — encoding plain text into HTML entities and decoding entity strings back to readable characters. The tool supports all standard named entities (like &amp; and &lt;) as well as numeric character references in both decimal and hexadecimal notation. This is essential for preparing user-generated content for safe HTML embedding, decoding scraped web content, encoding text for CMS fields, and converting special characters like copyright symbols and trademarks into their entity references. Everything runs in your browser, keeping your data private and the processing instant.

Frequently asked questions

All standard named HTML entities (like &amp;, &lt;, &gt;, &quot;, &copy;) plus numeric character references (decimal like &#169; and hexadecimal like &#xA9;) are supported in both directions.
No. All encoding and decoding happens entirely in your browser using JavaScript. Nothing is transmitted over the network.
Encoding special characters like <, >, and quotes into their entity equivalents is a fundamental XSS prevention technique. This tool helps you verify that user-generated content is properly escaped.
Named entities like &amp; are human-readable aliases. Numeric entities like &#38; use the character's Unicode code point. Both produce the same result in the browser. Named entities are preferred for common characters.
