What is URL Encoding? 

Online URL Encoding is also known as Percent Encoding refers to a procedure for encoding specific information in a Uniform Resource Identifier (URI). 

Moreover, it is used within the main Uniform Resource Identifier (URI) set containing Uniform Resource Locator (URL) and Uniform Resource Name (URN). 

In fact, the URL encoding is utilized in the preparation of data and even the submission of HTML form data with respect to HTTP requests. 

All the unallowable characters are changed and replaced with a percent sign (%) together with a two-digit hexadecimal value that signifies the character as used in the ISO character set. 

Here, we show some examples of URL Encoding: 

  • $ (Dollar Sign) becomes %24
  • & (Ampersand) becomes %26
  • = (Equals) becomes %3D
  • : (Colon) becomes %3A
  • + (Plus) becomes %2B
  • , (Comma) becomes %2C
  • ; (Semi Colon) becomes %3B
  • @ (Commercial At) becomes %40
  • ? (Question Mark) becomes %3F

Types of URI Characters

Characters acceptable in a URI are either reserved or unreserved. 

Reserved characters are the characters which have special meaning. A commonly used example of this is the slash character which is used to separate different parts of a URL.

However, unreserved characters have no special meaning. 

In percent-encoding, the reserved characters are represented with a unique character arrangement. 

There have been no major changes in the set of reserved and unreserved characters with each modification of specifications for URIs and URI schemes.
