What is URL Encoding?

URL encoding (also known as percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances.

Why is it needed? URLs can only contain certain characters from the ASCII character set. Characters outside this set must be encoded.

Examples:
Space → %20 or +
! → %21
@ → %40
# → %23
