Frequently Asked Questions
What are HTML entities?
HTML entities are special sequences like &lt; that represent characters that have special meaning in HTML. They prevent browsers from interpreting those characters as markup.
When should I HTML-encode text?
Any time you are inserting user-generated or untrusted text into an HTML document. Encoding prevents XSS attacks and ensures text displays correctly.
Is this secure?
Yes. All encoding and decoding happens locally in your browser. No data is transmitted.
