MIME::Types - Definition of MIME types


 use MIME::Types;
 my $mimetypes = MIME::Types->new;
 my MIME::Type $plaintext = $mimetype->type('text/plain');
 my MIME::Type $imagegif  = $mimetype->mimeTypeOf('gif');


MIME types are used in MIME entities, for instance as part of e-mail and HTTP traffic. Sometimes real knowledge about a mime-type is need. This module will supply it.



Create a new MIME::Types object which manages the data. In the current implementation, it does not matter whether you create this object often within your program, but in the future this may change.

 OPTIONS                   DEFAULT
 only_complete             0
  • only_complete => BOOLEAN

    Only include complete mime-type definitions: requires extension and encoding. This will reduce the number of entries --and with that the amount of memory consumed-- enormously.

    In your program you have to decide: the first time that you call the creator (new) determines whether you get the full or the partial information.


Return the MIME::Type which describes the type related to STRING. One type may be described more than once. Different extensions is use for this type, and different operating systems may cause more than one MIME::Type object to be defined. In scalar context, only the first is returned.


Returns the MIME::Type object which belongs to the FILENAME (or simply its filename extension). The extension is used, and considered case-insensitive.


 my MIME::Types $types = MIME::Types->new;
 my MIME::Type  $mime = $types->mimeTypeOf('gif');

 my MIME::Type  $mime = $types->mimeTypeOf('jpg');
 print $mime->isBinary;
addType TYPE, ...

Add one or more TYPEs to the set of known types. Each TYPE is a MIME::Type which must be experimental: either the main-type or the sub-type must start with x-.

Please inform the maintainer of this module when registered types are missing.


The next methods are provided for backward compatibility with MIME::Types versions 0.06 and below. This code originates from Jeff Okamoto <> and others.


Like mimeTypeOf but does not return an MIME::Type object.


 use MIME::Types 'by_suffix';
 my ($mediatype, $encoding) = by_suffix 'image.gif';

 my $refdata =  by_suffix 'image.gif';
 my ($mediatype, $encoding) = @$refdata;
by_mediatype TYPE

This function takes a media type and returns a list or anonymous array of anonymous three-element arrays whose values are the file name suffix used to identify it, the media type, and a content encoding.

TYPE can be a full type name (contains '/', and will be matched in full), a partial type (which is used as regular expression) or a real regular expression.


This method has been removed: mime-types are only useful if understood by many parties. Therefore, the IANA assigns names which can be used. In the table kept by this MIME::Types module all these names, plus the most often used termporary names are kept. When names seem to be missing, please contact the maintainer for inclussion.
