Percent-encode a parameter or a complete URL

Choose Encode or Decode, then select Component or Full URL. Component encoding uses the browser's encodeURIComponent behavior and is suited to an individual query parameter value: it encodes characters such as spaces, ampersands, question marks, and slashes. For example, hello world becomes hello%20world.

Full URL encoding uses encodeURI, which leaves URL structure characters such as :, /, ?, &, and # in place. Use it for a URL string, not for an individual parameter value. Decoding tries component decoding first, then full-URL decoding. Malformed percent escapes produce an error.

Encoding a parameter is not the same as encoding the entire query string: encode each key and value separately before joining them with = and &. Avoid encoding the same value more than once. Processing runs in your browser; entered text is not uploaded.
