Extract text from Windows Media videos (WM)
To convert WM videos to another format, you need Windows Media Player or other Video software.
To convert other file formats to the "Legacy Media Container" file type, you need software like Windows Media Player or a similar tool.
The .WM file extension has a highly fragmented history, primarily functioning as either a legacy Windows Media Audio/Video container or a Windows Movie Maker Project file. Originally developed by Microsoft, these files were designed to stream encoded media via Windows Media Player or save timeline edits in video projects. Occasionally, .WM files act as older screen capture outputs in TechSmith Camtasia or 2D motion simulation models in Working Model 2D.
Because .WM is a heavily deprecated proprietary format, modern users face severe compatibility limits. Contemporary media players, mobile devices, and web browsers cannot natively decode them without relying on obsolete codec packs. Furthermore, if the file is a Windows Movie Maker project, it does not actually contain video data - it only stores text references to local media, meaning direct conversion is impossible without the original software.
For actual media files, you must convert .WM to MP4 for universal web and mobile playback, or MKV for lossless archiving. Just drag and drop your file here to analyze and convert it - free, online, and without installing outdated software.

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.
