Drupal Convert File is a Drupal 7 module to automatically or manually convert existing or newly uploaded files into different formats. Conversion is done with a plugin system; "providers" each contribute various "formats" to which a file may be converted. The core module comes with providers: Google Drive, and ImageMagick. Two widgets will be installed: Convert File for file field types, and Convert Image for image field types. Field settings will have two new drop down options. The first selects the provider that will deal with transformation, the second specifies what format the provider should convert to.
