URL Encoder / Decoder
Encode or decode URLs and query values with percent-encoding, and inspect a URL's host, path and parameters.
How to use
- Paste text or a URL.
- Choose Encode or Decode, and whether you are encoding a single value or a whole URL.
- Copy the result. If the input is a URL, its parts are listed below.
What this tool does
Component mode uses encodeURIComponent (encodes / ? & = too) for query values; full-URL mode uses encodeURI and keeps the URL structure. Decoding can treat + as a space, as HTML forms do.
Frequently asked questions
When should I encode a URL?
Whenever you put user text, spaces or special characters into a query string or path, so they are not mistaken for URL syntax.
