Convert DI to another file type

Convert a file to DI

To convert other file formats to the "UML Diagram Interchange" file type, you need software like Eclipse Papyrus or a similar tool.

About DI files

The .di extension represents a "split personality" file type, creating confusion for users. In modern software development (approx. 29% of cases), it is a Papyrus Diagram Interchange file used by Eclipse Papyrus to store the visual layout of UML models. These are XML-based text files that contain coordinate data but not the actual model logic (which lives in a linked UML file). Opening them in a text editor just reveals raw XML code.

Alternatively, in legal and archiving contexts (approx. 7%), a .di file is a legacy Wang Annotation file. Popularized by "Imaging for Windows" in the 1990s, these files store sticky notes, highlights, and redactions overlaid on TIFF images. The critical problem: Modern image viewers often display the base image but ignore the .di sidecar file, meaning you might miss critical annotations or redacted info. Finally, in structural engineering, it may be a DICAD reinforcement drawing.

Best Conversion Targets:

For Papyrus: You cannot "convert" a standalone .di file. You must open the project in Eclipse and export the diagram to PNG or SVG for documentation.
For Wang/Legacy: Convert the .di + tif pair to a flattened PDF to permanently burn in the annotations.
For DICAD: Use STRAKON to export drawings to standard DWG or IFC formats for interoperability.

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

Users also converted DRAWIO, BPMN and EDG files.

The DI 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 DI converter.
