- application/octet-stream is the generic binary type when no precise type is known.
- For HTTP responses, use the appropriate value in the Content-Type header.
Frequently asked questions
Are MIME type and Content-Type the same?
The MIME type is the value used by the HTTP Content-Type header, which may also include parameters such as charset.
Does an extension guarantee the real type?
No. An extension is only a clue; the actual content may differ or be mislabeled.
Why do some types have no extension?
Some types mainly describe HTTP exchanges or multipart payloads and do not map to a regular file.
