How it works

The inspector decides whether your input looks like a media type (type/subtype, optionally with parameters) or a filename, then resolves it against a built-in table of registered and widely used MIME types. Content-Type values are parsed into type, subtype, structured syntax suffix and parameters, with warnings for non-standard x- or vendor vnd. names, missing charsets and generic fallbacks. Unknown extensions get close-match suggestions. Nothing is sent to a server.
