ABOUT

URL encode and decode with three standard methods

Non-ASCII characters, spaces and symbols such as & and ? must be percent-encoded inside a URL. This tool offers the three methods separately: encodeURI for a full address, encodeURIComponent for a single parameter, and form mode, which turns spaces into +. Picking the right one prevents broken query strings.

HOW TO

How to use it

  1. Enter the text or URL.
  2. Choose the method: URI for a full address, Component for one parameter, Form for form data.
  3. Copy the result; switch to decode to reverse it.
FAQ

Frequently asked questions

What is the difference between encodeURI and encodeURIComponent?
encodeURI leaves URL structure characters (:/?#&=) alone, while encodeURIComponent encodes them too, which is what you want for a parameter value.
Why is a space sometimes %20 and sometimes +?
+ means a space only in application/x-www-form-urlencoded data; in a URL path it must be %20.
