Knora API v2 currently supports using Sipi to store the following types of files:

* Images (JPEG, JPEG2000, TIFF, PNG), which are stored internally as JPEG2000
* PDF
* Images: JPEG, JPEG2000, TIFF, or PNG which are stored internally as JPEG2000

Support for other types of files will be added in the future.
