Key concepts

MIME type

Multipurpose Internet Mail Extensions type — a string like 'image/png' or 'application/json' that identifies the format of a file for HTTP and browser APIs.

Content-Type header

An HTTP header that tells the client or server what format the body is in — set using the file's MIME type string.
