Frequently Asked Questions
What are HTML entities?
HTML entities are special codes used to display reserved characters in HTML. For example, < represents < and > represents >. They prevent browsers from interpreting characters as HTML code.
When should I use HTML entities?
Use HTML entities when displaying special characters like <, >, &, quotes, or copyright symbols in HTML. They're essential when showing code examples or user-generated content to prevent XSS attacks.
What's the difference between named and numeric entities?
Named entities use memorable names like © for ©. Numeric entities use character codes like © (decimal) or © (hex). Both produce the same result, but named entities are more readable.
Should I encode all characters or just special ones?
For most cases, encoding only special HTML characters (<, >, &, quotes) is sufficient and keeps your HTML readable. Use "Encode all" when you need maximum compatibility or want to obscure text.
Is this tool free to use?
Yes! This HTML entity encoder/decoder is 100% free with no sign-up required and no limits on text length.
Is my data private?
