How to use

Paste text or a URL into the input box.
Choose Encode or Decode — the result updates instantly.
For a query-string value use the parameter mode; for a whole URL use the full-URL mode.

The two encoding modes

As a parameter value (encodeURIComponent) converts every reserved character including / ? = & — use this for search keywords or form values that will be embedded inside a URL. As a full URL (encodeURI) preserves the URL structure and only converts characters like spaces and non-ASCII letters — use this to encode a complete URL in one go.

Is my input sent anywhere?
