About WM files
The .wm extension is a notoriously ambiguous file type that typically serves two completely different purposes, causing frequent confusion. Most commonly, it is a Windows Media container - a shorthand for WMV (video) or WMA (audio) - often generated by legacy screen capture tools like TechSmith Camtasia or older versions of Windows Movie Maker. These files are essentially ASF (Advanced Systems Format) wrappers that struggle to play on modern non-Windows devices like iPhones, Macs, or Android phones without third-party tools like VLC Media Player.
Alternatively, in engineering and academic circles, a .wm file is a proprietary simulation model created by Working Model 2D. These files contain physics constraints, rigid bodies, and motion scripts, not video data. You cannot simply "convert" a simulation file to a video unless you open it in the original software and export the playback.
Conversion Recommendations:
For Video/Audio: Convert .wm media files to H.264 MP4 for maximum compatibility with web browsers and mobile devices, or MP3 if the file contains only audio.
For Simulations: If you have a Working Model file, you must open it in the software. To share the results, use the software's export feature to save as AVI or print the layout to PDF.

The WM 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 WM converter.
