online URL encoder decoder | URL encoder decoder`|Use the online tool from above to enter the code or specify a text string. For international collaboration, URIs should be coded accordingly. Mapping a wide range of characters used worldwide up to 60 characters or allowed in the URI, using a two-step process:

Convert a string of characters into a sequence of bytes using UTF-8 encoding
Convert each non-ASCII byte or digit byte to% HH, where HH is a hexadecimal byte value
For example, thread: François, would be encoded as Fran% C3% A7ois

This webpage is encrypted or decrypted using URL Encoding. URL Encoding is used when entering text with a query string to avoid confusion with the URL itself. The frequency is used when the browser sends form data to a web server. URL encoding, also known as Percent-encoding, is a way to enter information into a Uniform Resource Identifier (URI) under certain circumstances. Although known as URL encoding, it is, in fact, widely used within the main set of Uniform Resource Identifier (URI), which includes Uniform Resource Locator (URL) and Uniform Resource Name (URN). As a result, it is also used in data processing of "application / x-www-form-urlencoded" type data, as is commonly used in sending HTML form data to HTTP applications.

URL encoding refers to encoding certain characters in a URL. This is done by replacing them with at least one character try. All three contain the letter "%" percentage, followed by two hexadecimal digits. Two hexadecimal digits indicate the numerical approximation of the changed name.

The term URL encoding is not accurate because the encoding process is not limited to URLs. This also applies to some other URIs (uniform resource identifiers), such as URNs (uniform resource names). Therefore, the term percentage-encoding should be preferred.

Which characters are allowed in URLs?

Characters allowed in URI are not allowed or reserved. Especially meaningful characters are reserved characters. People who do not have reservations are not so important. Disallowed characters are displayed using allowed characters. Reserved and unreserved names have changed with each revision governing URIs.

Under RFC 3986, URL characters belong to the unsigned and reserved ASCII character set. Other characters are not allowed in the URL.

Uncoded characters are encoded but should not be encoded. Unreserved characters:

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 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 - _. I.

Reserved characters must be encoded only under certain circumstances. % # []

Encoding / decoding a piece of text

The RFC 3986 encoding table does not define any characters as non-ASCII characters. URL encoding consists of a pair of hexadecimal digits. Non-ASCII characters make it possible to use one of those 8-bit code pages (for example, to get ISO-8859-1 umlaut).

Many languages ​​have 8-bit code pages; These pages can be difficult to maintain. Some languages ​​may not even fit an 8-bit code page (e.g., Chinese). Therefore, RFC 3629 proposes to use the UTF-8 character encoding table. It accepts non-ASCII characters. The following tool will take this into account. It chooses between ASCII with the UTF-8 character encoding table. You select the ASCII character encoding table; A warning message will pop up.

When and why do you use URL encoding?

The information entered in the HTML form will be submitted. Form field names and values ​​are encoded and sent to the server in an HTTP request message. Encoding is based on the initial version of the general URI percentage-encoding rules. It uses a number of transitions, such as normalization and filling in the blanks with "+" instead of "% 20".

The MIME type data application encoded in this way is encoded / x-www-form-url. It is defined by HTML and XForms specifications. CGI web servers have rules on how to decode data and make it available to applications.

After sending the HTTP GET request, the application / x-www-form-url encoded information will be added. When HTTP POST is sent by request or email, the information is stored in the body of this message. This media type header is added to the content-type header message.
 

The free online URL Encoder / Decoder tool works when you enter a text string in the space provided at this link https://www.bitseotools.com/url-encoder-decoder. After that, all you have to do is click the "Encode" or "Decode" button, and it will show the results immediately.

This will be useful if you want to turn a JavaScript URL written in plain text into easy-to-read text. A URL usually contains a non-alphabetical alphabet or character to be assigned to “%” (percentage mark), followed by a few letters of the alphabet. After that, white spaces in the text will be encoded with a "+" sign.

URLs can only be transferred to the Internet using a set of ASCII characters. Since these URLs come with characters outside the ASCII set, the URL needs to be converted to an active ASCII format. This URL entry is used to replace unsecured ASCII characters with the percentage symbol (%) followed by two hexadecimal numbers. The encoding of the URL replaces the space by adding a plus sign (+) or by% 20.
