This article serves as covering all the key topics to be known on online URL encoding and decoding. It also illustrates the concept of URL online is encoding and decoding and performs as a handy source for beginners or the users who are often required to study up this material.


What is URL Encoding and How does it work?

A URL (basically stands for Uniform Resource Locator) is the address of a source on the world wide web i.e www. URLs possess a well-defined formation which was formed in RFC 1738 by the expert named Tim Berners-Lee. He is the inventor and the man behind this world wide web. URLs can just be transferred over the Internet utilising the ASCII character set. If any URL contains numbers outside the ASCII, the URL has to be changed. URL encoding changes non-ASCII signs into a form that can be forwarded over the web. URL encoding supplants non-ASCII figures with a “%” replaced by hexadecimal digits.

The URL shortening upon Meta-Wiki. URL shortening is a system or a plan on the World Wide Web www, in which a Uniform Resource Locator (i.e URL) may be executed substantially smaller and still straight to the required surface. This is accomplished by a redirect that links over the web page that owns a long URL.

Every URL looks like this -

URL Encoding (as in Percent Encoding)

A URL is formed from a limited set of parts relating to the US-ASCII set. These include letters(A-Z, a-z), digits (0-9), and some special attributes ( “.”, “~”, “-“, “_”).

ASCII control attributes (e.g. Backspace, horizontal tab, vertical tab, line feed etc), unsafe aspects like space,}, \, >, <, {,etc, and each kind outside the ASCII charset that is not supported to be placed straight within URLs. Furthermore, there are some cases that have specific meanings within URLs. These figures are described as reserved characters, for example, /, ?,:, #, etc. Each data transmitted as a portion of the URL must not include these characters.

URL encoding is further called per cent encoding as it uses per cent sign (%) being an escape character.

2. What About URL Encoder?

URL Encoder works as a Free SEO Tool that allows one to Encode with ease a string, which will be a component of a URL. This is beneficial when one wants to add any special characters to any URL parameter. This is basically a simple device that will benefit one in encoding or decoding a URL that can be securely utilised for links. URL encoding will replace unsafe ASCII marks with a “%” accompanied by two hexadecimal numbers.

URLs cannot include spaces. URL encoding usually replaces a space or area with a plus (+) symbol or by %20.

3. How does URL encoding work?

Remember, when dispensing with question strings and URLs, it is most useful to follow a three-step plan.

1. Find? the question mark in the question string to distribute the full URL within two parts.

2. Toward the left-hand side of that? apply rawurlencode to encode.

3. Toward the right-hand side of that? exert urlencode to encode.

With this method, one will drive their way around URLs, links, and PHP without difficulty.

URL Encoder or Decoder. This is basically a string that adheres to the Uniform Resource Locators Specification, which is URL (RFC 1738). Percent-encoding, also recognised as URL encoding, is a means to encode arbitrary data into a Uniform Resource Identifier (URI) utilising only the restricted US-ASCII characters allowed within a URI. although it is identified as URL encoding, it is likewise used more frequently within the central Uniform Resource Identifier (URI) circle, which covers both Uniform Resource Locator (URL) along with Uniform Resource Name (URN).

4. How does URL decoding work?

The word decoding may cause one to think of spies and undercover decoder rings. That creates sense as a written language really is a code. It utilises symbols (letters) to describe sounds.

How does URL Decoding work? Here are the rules that are applied for decoding path parameters, question strings, or HTML parameters:

The alphanumeric letters a - z, A - Z, and numbers from 0 - 9 do not switch and remain identical.

Safe figures like - ~, _and ~ too do not change and prevail the same.

Any order of the form %xy does treat being a byte in which XY is the two-digit hexadecimal description of the 8 bits. Next, every substring that includes one or more of those byte sequences sequentially is substituted by the figure(s) whose encoding might result in those following bytes.

4 steps on how to decode

To decode any website URL, One has to follow the following simple steps-

Step 1- First, one needs to choose the desired tool online in which they prefer to decode their particular URL.

Step 2- Second, they need to enter the text which has to be decoded or encoded.

Step3- Step-2: Write your text in the text area.

Step 4-: Press the “Submit” button.

That’s all that needs to be done in order to decode any website URL.

When should one need their URL encoded or decoded?

There are therefore many benefits of using the freely available online tools for encoder/decoder.

Directly, one should always encode or decode their URL, especially when the link or text includes non-alphabetic figures, numbers or any specific special aspects when not employed in their normal setting.

There are therefore many benefits of using the freely available online tools for encoder/decoder. Such as-

  • It is simple and comfortable to use.

One can easily begin the task by entering their data in a particular space of the tool. In barely a second, the outcome shall be shown to the user. one can also choose a file from the device when one needs it. Formerly the processing and transformation complete, one will be informed to download the transformed decoded/encoded file. That’s the only thing one has to arrange!

  • The goal of these tools is to implement the most simple and immediate URL encode and decode solution for average people, without the necessity to make any conclusions or configuration settings. one simply has to paste the data and drive the encode or decode key, that’s entirely done.
  • The tools are available online which are thus totally free to use. From now one doesn’t need to download or install any software for accomplishing such tasks. It is absolutely safe and secure. All communications of the data to the servers of such tools are undertaken through protected SSL encrypted connections (HTTPS).
  • Uploaded information is deleted from his or her servers shortly after the decode or encodes process. adding more to it, including the resulting downloadable data is deleted immediately after the initial download attempt.
  • The free online URL encoder/decoder available works so quick and easy that one doesn’t need to remember any computer jargon or code to carry out such tasks. This URL Encoder/ Decoder shall do all the technological steps for the users.
  • Moreover, one doesn’t require any website specialist to do this URL encoding and decoding task for them! Thus, this online work of URL Encoder Decoder profits people and entrepreneurs, who aspire to transform their URLs into a 100 per cent safe and secured readable form.

Important terms to know on URL Encoding and decoding …

  • The term “URL encoding or decoding ” isn’t exactly accurate because the encoding or decoding process is not restricted to URLs, however can be enforced to URIs (i.e Uniform Resource Identifiers) like that as URNs (i.e Uniform Resource Names) also. A more fitting term would be Percent-Encoding.
  • Since only around 60 characters are allotted or permitted in a URI, it is important to convert the wide range of characters employed worldwide into several allowed characters. A two-phase process is worn for this conversion:
  • The character cord is converted into a course of bytes utilizing UTF-8 encoding or decoding any byte that is not an ASCII letter or number is changed to %HH, (HH as the hexadecimal worth of the byte)

Allowed Characters to enter In any URI

Using per cent-encoding, numbers that would not usually be allowed are designated using provided characters.

According to RFC3986, any characters in a URL need to be obtained from a collection of unreserved and reserved ASCII figures (or the per cent symbol applied for per cent-encoding or decoding). No additional characters are permitted in a URL. Reserved cases sometimes have peculiar meaning, although unreserved characters of the cases don’t. Using per cent-encoding, numbers that would not usually be allowed are designated using provided characters.

One could decide to encode or decode the unreserved figures, though they should not be encoded. The unreserved figures mean to be mentioned as follows:


a b c d e f g h i j k l m n o p q r s t u v w x y z

0 1 2 3 4 5 6 7 8 9 – _ . ~

The reserved characters can be as mentioned below:

! * ‘ ( ) ; : @ & = + $ , / ? % # [ ]

These should be encoded or decoded under specific circumstances. Offending characters have to be superseded by a per cent symbol (%) and a two-numbered hexadecimal value that depicts the figure in the ISO number set. For instance:

  • $ (Dollar Sign) can be encoded as %24
  • & (Ampersand) can be encoded as %26 and then on…

By URL encoding or decoding, it becomes feasible to transmit those characters with specific meaning in a manner that is parsed as clear data.
