Common MIME types

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

Two primary MIME types are important for the role of 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 pay a particular care 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 a list of all the official MIME types. This table lists important MIME types for the Web:

.xml XML application/xml is recommended as of RFC 7303 (section 4.1), but text/xml is still used sometimes. You can assign a specific MIME type to a file with .xml extension depending on how its contents are meant to be interpreted. For instance, an Atom feed is application/atom+xml, but application/xml serves as a valid default.
