How it works

Convert text to HTML entities (so it's safe inside HTML) or decode HTML entities back to readable characters.

Encode mode replaces special characters with their HTML entity equivalents: < becomes &lt;, > becomes &gt;, & becomes &amp;, etc. Common named entities are used where they exist (&copy;, &reg;, &trade;, &euro;, &ndash;, &hellip;, &nbsp;), and other non-ASCII characters fall back to numeric entities (&#1234;). Decode mode uses the browser's own HTML parser (via a textarea element) to convert any entity, named or numeric, back to its character. Live as you type. Useful for safely embedding user input in HTML, sanitizing copy-pasted text from rich editors, or decoding entity-soup from email or legacy CMSes.

How to use it

1. Pick encode or decode. Encode makes text safe inside HTML; decode turns entities back into characters.
2. Paste your text. The conversion runs live — named entities where they exist, numeric fallbacks otherwise.
3. Copy the output. Everything happens in your browser, nothing is sent anywhere.

Frequently asked questions

Why use HTML entities?

To safely include characters that would otherwise be interpreted as HTML markup. < and > inside text become &lt; and &gt; so the browser shows them rather than treating them as tags.

Does it handle Unicode emoji?

Encode mode converts to numeric entities (&#128512;). Decode mode handles any entity the browser recognizes.

Is my text uploaded?

No. Encoding and decoding both happen in your browser.

Are all named entities supported?

Encode mode uses a curated set of common named entities; everything else falls back to numeric. Decode mode handles all browser-recognized entities.
