FAQ

Q: What is an HTML entity?
A: HTML entities are special character sequences used to represent characters that have special meaning in HTML or that are difficult to type. For example, < is written as &lt;, & as &amp;, and © as &copy;.
Q: When should I encode HTML entities?
A: Always encode user-supplied content before inserting it into HTML to prevent XSS (Cross-Site Scripting) attacks. Also encode when embedding special characters in HTML attributes or text nodes.
Q: What is the difference between named and numeric entities?
A: Named entities use human-readable names (e.g. &amp;copy; for ©). Numeric entities use decimal (e.g. &#169;) or hexadecimal (e.g. &#xA9;) code points. Both represent the same character; named entities are easier to read.
Q: Does decoding also handle numeric entities like &#169;?
A: Yes. The tool decodes both named entities (&copy;) and numeric entities (&#169; and &#xA9;) in Decode mode.
Q: Does this tool send my data to a server?
A: No. All encoding and decoding is performed in the browser. Your data is never sent to any server.
