Frequently Asked Questions
What are HTML entities?
HTML entities are special codes used to display reserved characters in HTML. For example, < is encoded as < so the browser does not interpret it as an HTML tag.
Why should I encode HTML entities?
Encoding prevents the browser from interpreting user input as HTML/JavaScript code, which protects against Cross-Site Scripting (XSS) attacks and ensures content displays correctly.
What is the difference between named, decimal, and hex entities?
Named entities use readable names like & for &. Decimal entities use the Unicode code point like &. Hex entities use hexadecimal like &. All three produce the same result.
Is my data secure?
Yes. All encoding and decoding happens entirely in your browser using DOM APIs. No data is sent to any server.
