What is URL Encoding and URL Decoding?

URL encoding is generally used in the query string or also known as the Uniform Resource Identifier (URI). Users only really want to use URL encoding on the special symbols. This free online URL Encoder/Decoder tool will do the job if you want to get your URL encoded or decoded.

What is the Use of URL Encoding?

The URL specification RFC 1738 states that only a small set of characters are allowed to be used in a URL. Those characters are listed below:


- (Hyphen or Dash)

a to z (abcdefghijklmnopqrstuvwxyz)

_ (Underscore)

0 to 9 (0123456789)

. (Period)

$ (Dollar Sign)

! (Exclamation or Bang)

+ (Plus sign)

* (Asterisk or Star)

( (Open Bracket)

' (Single Quote)

) (Closing Bracket)


How does URL Encoding work?

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
