Free HTML Encoder & Decoder

Convert characters to and from HTML entities. Encoding is essential when you display user input inside HTML to prevent XSS attacks; decoding helps you read raw HTML source or convert exported text back to its original form.

Features

How to use

  1. Step 1. Paste text or HTML-encoded content.
  2. Step 2. Click Encode or Decode.
  3. Step 3. Copy the result.

Frequently Asked Questions

Why escape HTML?

Inserting unescaped user input into a page lets attackers run JavaScript (XSS). Encoding turns dangerous characters into harmless entities the browser will display as text.

Does it handle named entities like ©?

Yes, decoding supports common named entities as well as numeric (') and hex (') forms.
