What Is URL Encoding?
URL encoding is the process of replacing special characters in a URL with a format that browsers and servers can safely interpret.
For example:
Original Text
Hello World
Encoded Version
Hello%20World
The space is replaced with %20, ensuring the URL remains valid.
Many characters cannot appear directly inside URLs because they have reserved meanings. Encoding converts these characters into a standardized format using hexadecimal values.
What Is URL Decoding?
URL decoding performs the opposite operation.
It converts encoded URLs back into their original readable text.
Example:
Encoded
https%3A%2F%2Fexample.com%2Fabout%3Fpage%3D1
Decoded
https://example.com/about?page=1
This makes URLs much easier to read, edit, and debug.
