Frequently Asked Questions
What is a MIME type?
A MIME type, or media type, is a label such as text/html or image/png that tells software what kind of content a file or response contains.
Where are MIME types used?
In the HTTP Content-Type header, in HTML form enctype, in email attachments, and anywhere a program needs to know the format of a file.
What is application/octet-stream?
It is the generic type for arbitrary binary data. Browsers usually download it instead of trying to display it.
Why is the MIME type for .docx so long?
Office files use a vendor (vnd) type that spells out the exact format, which is why the docx and xlsx types are so verbose.
