Introducing URL Encode, a straightforward online tool that effectively decodes and encodes data from URL encoding with ease. Encode your data into URL format effortlessly or decode it for easy readability.
URL encoding, also referred to as "percent-encoding", is a method used to encode information within a Uniform Resource Identifier (URI). While it is commonly associated with URLs, it is actually used more broadly within the overall URI set, which encompasses both URLs and URNs. This encoding technique is also utilized in formatting data for the "application/x-www-form-urlencoded" media type, which is frequently used when submitting HTML form data in HTTP requests.
Types of URI characters
The characters that can be included in a URI are categorized as either reserved or unreserved, with the option of using percent-encoding for special characters. Reserved characters often have specific functions, such as forward slashes separating parts of a URL. Unreserved characters do not hold any special significance. Through percent-encoding, reserved characters are replaced with special sequences. The definitions of reserved and unreserved characters, as well as the instances in which reserved characters have special meanings, have evolved with each update to the specifications governing URIs and URI schemes.
Percent-encoding reserved characters
When a character that is designated as reserved (a "reserved character") has a specific meaning (a "reserved purpose") in a certain context, and a URI scheme requires using that character for a different purpose, then that character must be encoded as a percent-encoded value. 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. These digits, preceded by a percent sign ("%"), are then used in the URI instead of the reserved character. (For a non-ASCII character, it is usually converted to its byte sequence in UTF-8, and then each byte value is represented as described above.)
