What characters does HTML encoding convert?

HTML encoding converts five key characters: becomes >, & becomes &, " becomes ", and ' becomes '. Any other Unicode character can also be encoded as a numeric entity.

When should I use HTML encoding?

Use HTML encoding whenever you need to display characters that HTML would interpret as markup. This includes showing code examples, displaying user-generated content safely, and putting special characters inside HTML attributes.

Is HTML encoding enough to prevent XSS?

HTML encoding is a critical part of XSS prevention but not sufficient alone. You must encode for the correct context (HTML body, attributes, JavaScript, CSS). This tool handles HTML body and attribute encoding. For complete protection, use a security framework with context-aware encoding.

What's the difference between named and numeric entities?

Named entities use readable names like & and <. Numeric entities use decimal (&) or hexadecimal (&) code points. Named entities are more readable in source code, while numeric entities work for any character including those without named equivalents.

Can I encode entire HTML documents?

Yes, you can encode entire HTML documents, but this would make the markup non-functional. HTML encoding is typically used for specific content within HTML, not for the HTML structure itself. Use it for content that needs to be displayed as text.
