What Is a MIME Type?
A MIME type (Multipurpose Internet Mail Extensions type), also called a media type, is a standard label that indicates the nature and format of a file or data stream. Originally designed for email attachments, MIME types are now fundamental to how web browsers, servers, and APIs communicate about content formats.
