How to Use HTML Entity Encoder

Paste the text or HTML you want to make safe into the input box.
Encode replaces reserved characters (& < > " ') with HTML entities so they render as text instead of markup; decode reverses it.
Choose named (&), decimal (&), or hex (&) entity output.
Copy the result. Nothing is uploaded — it is processed in your browser.

Encoding reserved characters prevents them from being interpreted as tags or breaking attributes, which also helps avoid injection when displaying user text.

Examples

Encode HTML — input:

<b>"Tom & Jerry"</b>

Output:

<b>"Tom & Jerry"</b>

Ampersand — input:

Fish & Chips

Output:

Fish & Chips

Decode (reverse) — input:

Output:

Decoding turns entities back into their original characters.
