HTML Entity Encoder / Decoder

What is HTML Entities?

HTML entities represent reserved characters. This encoder handles the four core entities plus numeric references, and decodes all named and numeric entities back.

How it works

We use the browser DOM parser for decoding and a character map for encoding, covering all HTML4 and HTML5 named entities.
