How to use the URL encoder/decoder

URL coding is generally used when the browser sends data to a web server. You can use our tool to automatically URL encode or decode a text string for global interoperability.

  • Step # 1: Copy and paste the URL or text string you want to encode or decode.
  • Step # 2: Encode the text: 'Reserved symbols' will be transformed into '%' symbols and two-digit hexadecimal values.

or

Decode the text: the gibberish string will be deleted and the text will be transformed into a readable format.

 

Why should I use the URL encoder/decoder?

URL coding and URL decoding, commonly known as 'percentage coding', change a string to respect the regulations imposed by the Uniform Resource Locator specification.

The RFC 1738 universal resource locator specification dictates that solely a little set of characters are often employed in a universal resource locator structure.

These characters are: uppercase letters (A to Z), lowercase letters (a), digits (0 to 9), as well as several "reserved" symbols (dollar sign, underline, period, closing/opening) square bracket, single quote, asterisk, exclamation, plus sign and dash).

All offensive characters must be replaced by a%, followed by the two-digit hexadecimal value represented by the symbol in the ISO character set (for example, @ becomes% 40); otherwise, you might have problems trying to pass information through a URL.

 

Why do we build this tool?

In the past, people manually encoded the special characters in their encoding string. This was a tedious task that would generally result in a human error. We build this tool to help you encode/decode URLs in seconds.

 

What is URL encoding?

URL encoding refers to the encoding of certain characters in a Uniform Resource Locator (URL). URL encoding is a two-step process: the character string is encoded in a sequence of bytes and then each byte that is not an ASCII letter or a digit is also converted to a hexadecimal value of the byte.

 

What are the reserved characters?

Sometimes, reserved characters have special meanings, and URL encoding allows them to maintain their special character sequences. In other words, if a reserved character has a reserved purpose in a given context, the URL scheme dictates that it is encoded in URL.

A URL encoding converts the character to its corresponding byte value in ASCII. This new value (two digits preceded by a%) will be used in the URL instead of the reserved character.

 

What is the purpose of the reserved characters?

Here is a list of reserved characters, their purpose, and coding:

% 3B

<space>

Space, not recommended in URLs.

+ o% 20

?

Separate query string

When should I encode the URL?

Strictly speaking, you should always encode the URL, especially if your link or text contains non-alphabetic characters, numbers or special characters that are used outside your normal context.

Should the URL encode unreserved characters?

Unreserved characters (upper and lower case, digits and symbols '-', '_', '.', '~') Can be encoded, but must not be encoded.
