Convert a file to MWI
To convert other file formats to the "Scientific Image Data" file type, you need software like Motic Images Plus or a similar tool.
About MWI files
The .mwi file format primarily functions as a digital microscopy image file. It is generated by laboratory imaging software, most notably Motic Images Plus and the open-source Micro-Manager. A secondary but common variation of the .mwi extension is a physiological data acquisition file used by hardware from MindWare Technologies and Movisens to log biometric sensor data. Additionally, it is occasionally used as a Music Macro Language data file by older FMP/PMD drivers.
These formats are highly proprietary and present significant challenges for users. Motic .mwi files contain specialized scientific metadata - such as spatial calibration, objective lens settings, and multi-channel exposures - that standard image viewers cannot read. This forces researchers to rely on specific, often expensive laboratory workstations just to view their data. Similarly, the physiological data versions lock raw metrics behind specialized analytical software, making independent analysis difficult.
Users frequently need to convert these files to share findings in publications or analyze data with standard statistical tools. For microscopy images, converting .mwi to TIFF is highly recommended to preserve uncompressed, lossless scientific data. For web publishing or basic reports, PNG or JPG are acceptable, though crucial spatial calibration data will be permanently lost. If you have a physiological .mwi file, converting the internal tables to CSV or XLSX is essential for processing the data in Python, R, or Excel.
Because the .mwi format is a closed, proprietary container, standard online image converters usually fail to process it. They lack the specific scientific codecs required to render the raw pixels or extract the underlying data tables. We inspect the file structure at a binary level to identify the exact format version. If our analysis detects an underlying SQL database framework or embedded standard image frames, viewing the contents or extracting the raw data may still be seamlessly possible.
Convert.Guru analyzes your MWI file, detects the exact format, and lets you read the text inside.

The MWI Converter Story
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 MWI converter.
