Extract text from MDI files
To convert your MDI file to another format, you need Microsoft Office or other Raster Image software.
To convert other file formats to the "Scanned Document Container" file type, you need software like Microsoft Office or a similar tool.
MDI (Microsoft Document Imaging) is a proprietary, legacy raster image format created by Microsoft to store scanned documents and optical character recognition (OCR) metadata. Introduced with Office 2003, these files are essentially a specialized wrapper around the TIFF format.
A key problem with .MDI files is their obsolescence; Microsoft deprecated the Microsoft Office Document Imaging (MODI) tool in Office 2010, leaving modern users unable to open these files with standard image viewers or current versions of Microsoft Word. This proprietary lock-in means important archival data is often inaccessible without legacy software or specific converter tools. Additionally, .MDI files are not supported by web browsers or mobile devices.
To regain access to your documents, the best solution is converting .MDI to PDF for archiving and sharing, as this preserves the multi-page structure and document integrity. For image editing or extraction, converting to standard TIFF, JPG, or PNG is recommended.
Convert.Guru analyzes your MDI file, detects the exact format, and lets you read the text inside.
Users also converted MID, TIF, MD, MP3, PNG, PDF, JPG, MSI, SIG, PLA, XRDML, STEP and CDW files.
If you want to convert MDI file to PDF, TIFF, JPG, INDD, QXP, PUB, PMD, PM6, PM7, PM8, PM9 or PM10, you can use Microsoft Office or similar software from the "Scanned Document Storage" category. In the File menu, look for Save As… or Export….
To convert PUB, PDP, PM4, P65, COMIC, WEBTEMPLATE, PMD, SPUB, INDD, PM5, QXP or OMP files to MDI, try Microsoft Office or another comparable tool in the "Scanned Document Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MDI converter.
