MIME types: Complete list of MIME types

Here is a list of MIME types, associated by type of documents, 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, attempting to safeguard the user to prevent dangerous behaviors.
