Frequently Asked Questions
What is HTML encoding?
Replacing characters that have special meaning in HTML (< > & " ') with entity codes so they display as text instead of being parsed as markup.
When should I encode HTML?
Whenever you display user input or code samples inside a web page — it prevents broken layouts and cross-site scripting (XSS).
What's the difference between named and numeric entities?
Named entities like & are readable; numeric ones like & cover every Unicode character. This tool emits named entities where standard ones exist.
Can it decode double-encoded entities?
Yes — run decode twice to unwrap &lt; style double encoding.
Is it free?
Yes — free forever, no signup.
