The difference between MDI and other image formats is the proprietary nature as you can only manage the file by using MS Office Document Imaging. The format is also capable of OCR text recognition and Send text to word on detection. The Microsoft Document Imaging Format ( MDI for short) is a TIFF based file format but proprietary for Office Document Imaging and it is used for storing images by using the page layout. If you have a MDI file you want converted to PDF, Microsoft provides a tool to convert MDI files to TIFF (the tiff format is currently supported). The article below applies to older versions of Office.


Microsoft Office Document Imaging (MDI) was discontinued in 2009 thus it is not supplied with Office 2010 or Office 2013 anymore.
