About URL Decoding

What is URL Decoding?

URL decoding converts URL-encoded characters back into their original format. URLs can only be sent over the Internet using the ASCII character-set, so special characters are encoded using a "%" followed by two hexadecimal digits.

URL decoding reverses this process, converting encoded characters (like "%20" for a space) back into their original form, making the URL human-readable and easier to process programmatically.

Common Use Cases

  • Decoding URL parameters received from web forms
  • Processing query strings in web applications
  • Decoding API response URLs
  • Debugging encoded URLs
  • Working with encoded data in legacy systems

URL Decoding Examples

Special Characters

%20 → Space ( )
%3F → Question mark (?)
%26 → Ampersand (&)
%3D → Equals sign (=)
%2B → Plus sign (+)
