A URL decoder is a tool that reverses the process of URL encoding (also known as percent-encoding). Here's what that means:

1. URL Encoding Explained:

   • When data is sent in a URL (for example, in query parameters), certain characters (like spaces, punctuation, or non-ASCII characters) might cause issues or be misinterpreted by web servers and browsers.
   • To handle this, these characters are encoded into a specific format. For instance, a space is encoded as %20, and a question mark as %3F.

2. Purpose of a URL Decoder:

   • A URL decoder takes an encoded URL string and converts those encoded sequences back into their original characters.
   • This conversion makes the URL human-readable and easier to understand or debug, especially when checking the values of parameters in the URL.

3. Usage Scenarios:

   • Web Development: Developers use URL decoders to troubleshoot issues related to data being passed through URLs.
   • Security Analysis: Analysts might decode URLs to reveal hidden or obfuscated parameters.
   • Everyday Tools: There are many online URL decoder tools where you can paste an encoded URL and get the decoded version instantly.

Example:
Suppose you have the following encoded URL parameter:
