Extract text from Gamebryo and Killing Floor files (KFM)
To convert KFM Game files to another format, you need Gamebryo Engine or other Game software.
To convert other file formats to the "Game Engine Asset" file type, you need software like Gamebryo Engine or a similar tool.
The .KFM file extension primarily represents a Gamebryo Animation Manager File used by the Gamebryo game engine. In this framework, the file does not hold 3D geometry itself but acts as a bridge, linking a 3D model (often a NIF file) with its corresponding animation sequences (KF files). A secondary, but widespread use for the .KFM extension is as a Killing Floor Game Map, built by Tripwire Interactive on a modified Unreal Engine 2.5.
These files present a massive challenge for everyday users. They are closed, proprietary formats tied to heavy, legacy game engines. You cannot open a Gamebryo .KFM file in standard 3D viewers, nor can you easily view a Killing Floor map without the full game installed. Modders often need to convert .KFM data to standard 3D formats like FBX or OBJ for editing, or extract the contents to ZIP for distribution.
Because these formats rely on complex, engine-specific binary structures, standard online converters fail completely. Usually, only the original game engine SDK or specialized community tools like NifSkope can properly read or export the 3D data. Our system inspects the binary headers to determine if you have an animation index or a map file, extracting readable text strings. If our analysis detects a supported underlying structure, partial extraction or conversion may still be possible.
Convert.Guru analyzes your KFM file, detects the exact format, and lets you read the text inside.
Users also converted NIF, AZW, KFX, JPG, NSB and TCA files.
If you want to convert KFM file to OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL, PLY or WRL, you can use Gamebryo Engine or similar software from the "Game Animation & Map Data" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to KFM, try Gamebryo Engine or another comparable tool in the "Game Animation & Map Data" category.
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 KFM converter.
