The reserved character "/", for example, if used in the "path" component of a URI, has the special meaning of being a delimiter between path segments. (For a non-ASCII character, it is typically converted to its byte sequence in UTF-8, and then each byte value is represented as above.) The digits, preceded by a percent sign "%" which is used as an escape character, are then used in the URI in place of the reserved character. Percent-encoding a reserved character involves converting the character to its corresponding byte value in ASCII and then representing that value as a pair of hexadecimal digits. When a character from the reserved set (a "reserved character") has special meaning (a "reserved purpose") in a certain context, and a URI scheme says that it is necessary to use that character for some other purpose, then the character must be percent-encoded. RFC 3986 section 2.3 Unreserved Characters (January 2005) A The sets of reserved and unreserved characters and the circumstances under which certain reserved characters have special meaning have changed slightly with each revision of specifications that govern URIs and URI schemes. Using percent-encoding, reserved characters are represented using special character sequences. Unreserved characters have no such meanings. For example, forward slash characters are used to separate different parts of a URL. Reserved characters are those characters that sometimes have special meaning. How does URL encoding work All offending characters are replaced by a and a two digit hexadecimal value that represents the character in the proper ISO character set. The characters allowed in a URI are either reserved or unreserved. ![]() ![]() As such, it is also used in the preparation of data of the application/x-www-form-urlencoded media type, as is often used in the submission of HTML form data in HTTP requests. ![]() Although it is known as URL encoding it is, in fact, used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource Locator (URL) and Uniform Resource Name (URN). Percent-encoding, also known as URL encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. The online decoder tool takes the encoded URL as input and outputs the decoded URL. This is done to ensure that the URL is properly formatted and can be transmitted over the internet. The urldecode () function is an inbuilt function in PHP which is used to decode url which is encoded by encoded () function. The URL encoding process replaces certain characters in a URL with their corresponding ASCII code. Our online URL decoder tool helps you to convert an encoded URL into a readable format.
