HTML Entities Encoder and Decoder

Convert special characters into safe HTML entities to prevent XSS or rendering issues, and decode them back to readable text. Optional mode encodes every non-ASCII character as a numeric entity, useful for email templates and ASCII-only systems.

How it works

Encode: we replace each special character with its named entity (&, <, >, ", ', etc.). Optional all-chars mode encodes every code point above 127 as &#NNN;. Decode: we walk both named entities and numeric forms (&#decimal; and &#xhex;) back to characters via String.fromCodePoint.

How to use it

  1. Paste text or entities

    Drop in raw HTML or a snippet with entities. The tool detects whether you want to encode or decode based on the toggle.

  2. Pick named or all-chars

    Named replaces &<>"' with their named entities. All-chars also encodes every code point above 127 as &#NNN; for ASCII-only systems.

  3. Run the conversion

    Encoding swaps specials for entities. Decoding walks named (&amp;) and numeric (&#decimal; or &#xhex;) forms back to characters.

  4. Copy the safe output

    Take the entities into an HTML page, an email template that strips Unicode, an RSS feed, or anywhere XSS-safe escaping matters.

Use cases

Decode an HTML snippet copied from a CMS.

Embed an emoji in an email template that strips Unicode.

Read what a &amp;#x2014; really means.
