Frequently Asked Questions

What are HTML entities?
HTML entities are special codes that represent characters which have special meaning in HTML (like < and >) or characters not easily typed on a keyboard (like copyright symbol or em dash). They start with & and end with ; - for example, &lt; represents the less-than sign <.
Why do I need to encode HTML entities?
Encoding prevents browsers from interpreting special characters as HTML markup. Without encoding, a < in your text could be treated as the start of an HTML tag, breaking your page layout or creating XSS security vulnerabilities.
What is the difference between named and numeric entities?
Named entities use a human-readable name (like &amp; for &), while numeric entities use the Unicode code point (like &#38; for &). Both produce the same result, but named entities are easier to read in source code.
Does this handle all HTML entities?
Yes. The encoder converts all special characters to their HTML entity equivalents, and the decoder handles both named entities (like &copy;) and numeric entities (like &#169;). The quick-reference table covers the 25 most commonly used entities.
Is this tool free?
Yes, completely free with no signup required. All processing happens in your browser - your text is never sent to any server.
