Online URL encoding or Percent-encoding, is a procedure for encoding specific information in a Uniform Resource Identifier (URI) in definite situations. Even though it is widely known as known as URL encoding, in general, it is used within the main Uniform Resource Identifier (URI) set, which contains both Uniform Resource Locator (URL) and Uniform Resource Name (URN).
This online URL encoding is also utilized in the preparation of data and the submission of HTML form data in HTTP requests.
All characters that needs to be changed are replaced by a percent sign (%) and a two-digit hexadecimal value that signifies the character in the appropriate ISO character set. Listed below are some examples:
|$ (Dollar Sign) becomes %24
||+ (Plus) becomes %2B
|& (Ampersand) becomes %26
||, (Comma) becomes %2C
|: (Colon) becomes %3A
||; (Semi-Colon) becomes %3B
|= (Equals) becomes %3D
||? (Question Mark) becomes %3F
|@ (Commercial A / At) becomes %40
