HTML Entity Encoder

HTML entities are stand-in codes for characters that would otherwise have special meaning in HTML. They start with an ampersand and end with a semicolon, like & for an ampersand or < for a less-than sign.

Characters like <, > and & control how a browser parses HTML. If you want them shown as literal text instead of treated as tags or entity starts, you have to encode them so the page renders what you actually typed.

Named entities use a readable label, such as &amp; or &quot;. Numeric entities use the character's Unicode code point, such as &#233; for an accented e. This tool uses named entities for the core characters and numeric entities for everything above ASCII.

Escaping the reserved characters is a key defense against cross-site scripting when you insert untrusted text into HTML, because it stops that text from becoming live tags or attributes. It is one important layer, not a complete fix, so still use context-aware escaping and a content security policy.

Each entity itself contains an ampersand, so the tool replaces every literal & before adding the others. That prevents double-encoding, where &lt; would wrongly become &amp;lt;.

No. The encoding runs entirely in your browser, so your text never leaves your device.
