FIELD NOTES

Why HTML entities matter

Entities represent characters that otherwise have structural meaning in HTML. Escaping them lets code examples and literal symbols display as text.

Entity encoding alone is not a complete XSS defense. Applications must escape values for the exact HTML, attribute, URL or script context.

REFERENCE

Common questions

Does encoding make untrusted HTML safe?

Not universally. Use framework escaping and a trusted sanitizer when rendering user-provided markup.

Does this tool upload my input?

No. Processing uses browser APIs and the input is not sent to our server.
