This topic lists the most common MIME types with corresponding document types, ordered by their common extensions.

The following two important MIME types are the default types:

• text/plain is the default value for textual files. A textual file should be human-readable and must not contain binary data.
• application/octet-stream is the default value for all other cases. An unknown file type should use this type. Browsers are particularly careful when manipulating these files to protect users from software vulnerabilities and possible dangerous behavior.

IANA is the official registry of MIME media types and maintains alist of all the official MIME types. This table lists important MIME types for the Web:
