An Internet media type, originally called a MIME type after MIME (Multipurpose Internet Mail Extensions) and sometimes a Content-type after the name of a header in several protocols whose value is such a type, is a two-part identifier for file formats on the Internet.
A media type is composed of at least two parts: a type, a subtype, and one or more optional parameters. For example, subtypes of
text type have an optional
charset parameter that can be included to indicate the character encoding, and subtypes of
multipart type often define a
boundary between parts.
Types or subtypes that begin with
x- are nonstandard (they are not registered with IANA). Subtypes that begin with
vnd. are vendor-specific; subtypes in the personal or vanity tree begin with
MIME is short for Multipurpose Internet Mail Extensions, a specification for formatting non-ASCII messages so that they can be sent over the Internet. Many e-mail clients now support MIME, which enables them to send and receive graphics, audio, and video files via the Internet mail system.
There are many predefined MIME types, such as GIF graphics files and PostScript files. It is also possible to define your own MIME types.
MIME was defined in 1992 by the Internet Engineering Task Force (IETF). A new version, called S/MIME, supports encrypted messages.
