Frequently asked questions

What is the difference between encode and decode?

Encode turns special characters like <, > and & into safe HTML entities such as &lt;. Decode reverses it, turning entities back into readable characters.

Why do some characters become numbers like &#169;?

Common characters use named entities like &copy;. Anything without a standard name gets a numeric code, which every browser renders correctly.

Is my code sent to a server?

No. All encoding and decoding happens locally in your browser with JavaScript. Nothing you paste ever leaves your device.
