What are HTML Entities?
HTML entities are special codes used to represent characters that have reserved meaning in HTML or cannot be typed directly. They start with & and end with ; — for example, < represents <, & represents &, and " represents ". Numeric entities like < and hex entities like < are also supported.
How to Encode or Decode HTML Entities
Paste your text in the input area and click Encode to convert special characters into their HTML entity equivalents. Click Decode to convert entities back to readable characters. This tool supports named entities (&, <, >), decimal numeric entities (<), and hexadecimal entities (<).
Why HTML Entity Encoding Matters
Encoding HTML entities is essential for preventing cross-site scripting (XSS) attacks. Any user-supplied data displayed on a web page should be HTML-encoded to neutralize potential script injection. It is also used to display characters like <, >, and & in HTML content without breaking the markup.
