About HTML Entity Encoder / Decoder

This tool lets you escape html characters online before placing untrusted or special text inside HTML markup, and just as easily reverse the process. Reserved characters such as &, <, >, and quote marks can otherwise break a page's structure or open the door to injection issues if left unescaped.

Decoding uses your browser's own built-in HTML parser rather than a hand-written lookup table, so this html entities converter free tool correctly understands the full set of named entities, like &copy;, alongside numeric entities like &#39; and &#x27;.

How to Use

  1. Choose Encode to escape plain text, or Decode to turn entities back into text.

  3. In Encode mode, turn on Encode all non-ASCII characters too if you need fully ASCII-safe output.
  4. Click Copy Output to copy the result to your clipboard.

Why Use This HTML Entities Converter Free Tool

Full Named Entity Support

Decoding relies on the browser's native parser, so obscure named entities are recognized correctly, not just the five basic reserved characters.

Named and Numeric

Both decimal references like &#39; and hexadecimal references like &#x27; decode correctly every time.

Live Character Statistics

Input and output character counts update instantly, making it easy to spot how much an encoding pass expanded your text.

Zero Server Communication

Every conversion runs locally in your browser tab, so nothing you paste is ever transmitted over a network.
