Frequently asked questions

What's the difference between "Escape" and "Entities"?
Escape encodes only the four or five markup-significant characters — < > & " ' — which is what you need to safely put text inside HTML. Entities mode also encodes accented letters and symbols (é, ©, →) into references, useful for legacy encodings or ASCII-only contexts.
What do named, decimal, and hex output do?
They control how encoded characters are written. Named uses references like &eacute; and &amp;. Decimal uses numeric references like &#233;. Hex uses &#xe9;. All three decode back to the same characters; named is the most readable, numeric the most portable.
Can it decode entities back to plain text?
Yes. Switch to Decode and it converts named, decimal, and hexadecimal references — &lt;, &#233;, &#x41; — back to the original characters, whichever style they were written in.
Why should I escape HTML entities?
Rendering untrusted text without escaping < > & lets it break your markup or inject scripts (XSS). Escaping turns those characters into harmless references so the text displays literally instead of being parsed as HTML.
Is my text uploaded anywhere?
No. Encoding and decoding run entirely in your browser with JavaScript — nothing is uploaded, logged, or stored. It's free with no sign-up; a single unobtrusive ad slot covers hosting.
