Frequently Asked Questions

What are HTML entities?
HTML entities are sequences of characters used to display reserved characters (like < or >) and invisible characters in HTML without breaking the browser parser. They begin with an ampersand (&) and end with a semicolon (;).
How does HTML entity encoding prevent Cross-Site Scripting (XSS)?
By escaping special characters (converting <script> to <script>), the browser renders the characters as plain text instead of executing them as live code, which mitigates injection vulnerabilities.
Can I decode HTML entities back to plain text?
Yes, the tool works bi-directionally. You can paste HTML-encoded strings to escape them, or paste raw text to decode them back.
Does it support both named and numeric HTML entities?
Yes, the tool supports named entities (like & or <) as well as decimal (&) and hexadecimal (&) character references.
