HTML Entity Encode/Decode

Encode or decode HTML entities.

How to use

Encoding HTML entities

Converts characters that have special meaning in HTML into their safe entity equivalents: < → &lt;, > → &gt;, & → &amp;. Use this before inserting user-provided text into HTML to prevent XSS.

Decoding HTML entities

Converts entities back to their original characters. Useful when parsing HTML content from an API or web scrape where entities appear literally in the text.

XSS prevention

Always encode user-supplied content before rendering it in HTML. Even a string that looks harmless can contain <script> tags or event handlers that execute when the browser parses the page.
