2
The correct MIME type string appears instantly.
3
Copy the MIME type to use in your Content-Type header or server config.

Frequently Asked Questions

What is a MIME type used for?

MIME types tell browsers and servers what kind of content a file contains. They are used in HTTP Content-Type headers, email systems, and file validation.

What if my file extension is not in the list?

For unlisted types, use application/octet-stream as the generic binary MIME type.

Is this MIME type checker free?

Yes. Completely free with no account required.
