What is URL Encoder / Decoder?
A URL encoder/decoder converts text to and from percent-encoding (also called URL encoding), which is the format required for safely including special characters in URLs. Characters outside the unreserved set (letters, digits, -, _, ., ~) must be percent-encoded using their hexadecimal code points prefixed by %. For example, a space becomes %20, & becomes %26, and = becomes %3D. URL encoding is essential when constructing query strings, embedding user input in URLs, working with REST API endpoints that accept special characters in parameters, encoding redirect URLs, and processing form data submitted via HTTP GET requests. The decoder reverses the process, converting %XX sequences back to their original characters.
