How it works

The lookup maps common web, document, media and font extensions to their IANA-registered media types, and searches in reverse when you paste a MIME type instead.

Frequently asked questions

Why does the MIME type matter?

Browsers decide how to render or download a file from the Content-Type header, not the file name.

What about unknown files?

Serve application/octet-stream, which forces a download rather than a guess.
