What is a MIME Type?
A MIME type (Multipurpose Internet Mail Extensions) is a standard label used to indicate the nature and format of a file. It consists of a type and subtype separated by a slash (e.g., application/json). MIME types are used by web servers, browsers, and APIs to determine how to handle files.
