How to use url encoder/decoder


URL encoding is generally used when the browser sends data to a web server. You can use our tool to URL encode or automatically 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 hex values.
or

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

Why should I use URL Encoder/Decoder?


URL encoding and decoding, commonly known as 'percent encoding', alters a string to comply with the regulations imposed by the Uniform Resource Locator specification.

The RFC 1738 Universal Resource Locator specification dictates that only a small set of characters is often employed in a Universal Resource Locator framework.

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

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

Why did we build this tool?


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

What is URL encoding?


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

What are the reserved characters?


Reserved characters sometimes have special meanings and URL encoding allows them to retain 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 be encoded in a URL.

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

What is the purpose of reserved characters?


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

character

Character Purpose of URL Character encoding
/ Used to separate domains and directories % 2F
# Separate anchors %23
+ Indicate a space % 2B
% Indicates an encoded character %25
@ Separate user details and pass domain %40
: Address separate protocol % 3B
<space> Space, not recommended in URLs. + o% 20
? Separate query string % 3F

 

 

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 of their 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.
