What is HTML Encoder/Decoder?

HTML special characters like <, >, &, and " must be encoded as HTML entities (&lt;, &gt;, &amp;, &quot;) to display correctly in browsers and prevent Cross-Site Scripting (XSS) attacks. DailyDevTools' HTML Encoder/Decoder instantly converts text containing HTML special characters to safe entity-encoded HTML, and decodes encoded HTML back to readable text.

How to use HTML Encoder/Decoder

  1. 1Paste your text or HTML into the input field
  2. 2Click Encode to convert characters like <, >, &, ", and ' to their HTML entity equivalents
  3. 3Click Decode to convert HTML entities (&amp;, &lt;, &#39;, etc.) back to their original characters
  4. 4Use the output for safely rendering user input in HTML pages or escaping content for attributes
