Why do we encode URLs?

URLs can only be sent over the Internet using the ASCII character set. Any characters outside of this set, such as spaces or special symbols, must be converted into a valid ASCII format.

Percent Encoding

URL encoding is also known as "Percent Encoding". Spaces are converted into %20, and an ampersand is converted to %26, ensuring browsers and web servers route traffic safely without syntax errors.
