Convert MRB to another file type

To convert MRB bundles to another format, you need 3D Slicer or other 3D software.

Convert a file to MRB

To convert other file formats to the "Medical Imaging Archive" file type, you need software like 3D Slicer or a similar tool.


About MRB files

The .mrb extension typically refers to a Medical Reality Bundle, a data container used by the open-source platform 3D Slicer. These files are crucial for packaging medical imaging scenes, combining the scene description (MRML) with the actual volumetric data (like .NRRD or VTK files) into a single archive. The primary problem is that while portable, they require specialized medical software to visualize, making them inaccessible to standard image viewers or web browsers. A practical workaround is that .mrb files are often just ZIP archives; renaming the extension usually allows you to extract the raw 3D models or scan data for conversion to STL or OBJ.

Alternatively, in developer environments, this file represents mruby Bytecode. Unlike standard text-based Ruby scripts (.rb), these are compiled binary files optimized for embedded systems. They are not human-readable and cannot be edited in text editors like VS Code. Users often need to "convert" these back to source code (decompilation) or execute them using the mruby CLI. Less frequently, you may encounter an .mrb file generated by MRI Software for real estate reporting, which is a proprietary format often best converted to PDF via the original software's print function for archiving.

Convert.Guru analyzes your MRB file, detects the exact format, and lets you read the text inside.

Users also converted MBR, EBX, CKB and BPC files.

The MRB 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 MRB converter.
