How it works
Your browser reports a MIME type based only on the file extension (and your operating system's settings); it's empty for unknown extensions. KadiTools reads the file's signature to find its real format and the matching IANA MIME type, and shows how to declare it on Apache, nginx and in an HTTP response.
