What Is URL Encoder/Decoder?
Encode and decode URL strings with percent-encoding.
URLs can only contain a limited set of ASCII characters. Special characters (spaces, &, =, ?, #) must be percent-encoded — replaced with a % followed by their two-digit hex value. For example, a space becomes %20 and & becomes %26. This is essential when constructing query strings, API parameters, and embedding URLs inside other URLs.
