What is URL Encoding/Decoding?

URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. URL encoding is used to convert characters into a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%\" followed by two hexadecimal digits.

URL decoding is the reverse process, converting the percent-encoded URL back into its original form.
