HTML Encoder & Decoder
This tool helps you encode text to HTML entities and decode HTML entities back to plain text. It's useful when you need to safely display HTML content or decode HTML entities in your text.
What is HTML Encoding?
HTML encoding converts special characters to their HTML entity equivalents. This is useful when you need to display HTML content as text without the browser rendering it as HTML.
For example:
<becomes<>becomes>&becomes&"becomes"'becomes'
Common use cases include:
- Displaying code snippets on websites
- Preventing XSS (Cross-Site Scripting) attacks
- Ensuring HTML is displayed as text rather than rendered by the browser
- Processing user input that may contain HTML for safe display

Usage tips
- Entity encoding is context-dependent; HTML text, attributes, URLs, CSS, and JavaScript require different escaping rules.
- Do not decode untrusted content and then insert it with innerHTML without sanitization.
- Encode once at the output boundary to avoid double-encoded values such as &amp;amp;.
