What is URL decoding?

URL decoding is the process of converting a percent-encoded string back into its original, human-readable format. It translates character sequences that start with a '%' sign (e.g., '%20') back into their corresponding special characters (e.g., a space). This is the reverse operation of URL encoding and is essential for interpreting data passed in URLs.

When is it necessary to decode a URL?

You need to decode a URL or its parameters when your web application receives data from a form submission (GET request) or in the query string of a URL. Server-side scripts and client-side JavaScript often need to decode these values to read them correctly and use the data, as the raw encoded string would not be meaningful for application logic or for displaying to a user.
