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. 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 encoder takes a regular URL as input and outputs the encoded URL. This process is known as URL encoding and it helps to ensure that the URL is properly formatted and can be transmitted over the internet. Our online URL encoder tool transforms regular, readable characters in a URL into their corresponding ASCII code.
