FAQ

URL Encoder and Decoder: questions and answers

Something else? Ask us.

What is URL encoding?

URL encoding (percent-encoding) replaces characters that are not allowed or have a special meaning in a URL with a % sign and their byte value in hexadecimal. A space becomes %20 and “é” becomes %C3%A9.

What is the difference between encoding a component and a full URL?

Component mode (like encodeURIComponent) also encodes / ? & = and #, which is right for a single query value. Full-URL mode (like encodeURI) leaves those characters alone so the address keeps working.

Why do some URLs use + for spaces?

HTML forms encode spaces as + in query strings (application/x-www-form-urlencoded). Turn on “Treat + as a space” when decoding such values.
