Convert IDM to another file type
To convert IDM files to another format, you need Adobe InDesign or other Page Layout software.
Convert a file to IDM
To convert other file formats to the "Markup Language Document" file type, you need software like Adobe InDesign or a similar tool.
About IDM files
The .idm file extension is a technical anomaly often shared between two distinct professional industries: desktop publishing and building performance simulation. Most frequently (approx. 20%), an .idm file is actually an InDesign Markup Language file that has been mislabeled or truncated from the standard IDML extension. These are ZIP-compressed archives containing XML data, used to save Adobe InDesign documents in a version-agnostic format. Users frequently experience issues here; attempting to open a .idm directly in InDesign may fail or trigger a generic import error because the software expects the full four-letter extension.
Alternatively, the file may be a BIM data exchange file generated by IDA ICE (Indoor Climate and Energy), a dynamic simulation tool for modeling building thermodynamics. In this context, the file is a 7z compressed archive containing model geometry, HVAC systems, and climate data. These files are proprietary and functionally locked to the IDA ecosystem, making them impossible to view without the specific simulation software or a compatible viewer.
Best Conversion Targets:
For InDesign Files: If the file is a misnamed markup document, simply renaming the extension from .idm to idml is often the fastest fix. For viewing without Adobe software, convert the valid IDML to PDF or a raster format like PNG for quick proofs.
For IDA ICE Models: To share building data with other CAD tools, converting the proprietary model to IFC (Industry Foundation Classes) is the standard workflow. For result data, export to XLSX or CSV for analysis in spreadsheets.
For Game Archives: Files from Quantum Break or Quantic Dream titles are binary archives used internally by the game engine and are generally not convertible for end-user consumption.

The IDM 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 IDM converter.
