Convert PMX files online for free
The converter easily converts your PMX file to various formats - free and online. No Blender or extra software needed.
The converter also works in reverse, so you can convert other 3D formats to PMX with high quality output.
The .PMX file format is the standard 3D model container for MikuMikuDance (MMD), a popular freeware animation program. This format, which succeeded the older PMD standard, encapsulates complex character data including polygon meshes, vertex weights, bone rigging for animation, morph targets (facial expressions), and material references.
While .PMX is optimal for the MMD ecosystem, it presents significant barriers for creators working outside of it. The format is heavily proprietary and does not open natively in industry-standard software like Blender, Maya, or game engines like Unity and Unreal Engine. Users often face friction with broken textures (Toon/Sphere maps), incompatible bone structures, or the need to install complex third-party plugins just to view the geometry. Additionally, legacy project files from PrintMaster occasionally use this extension, creating confusion.
To overcome these limitations, converting .PMX is essential for broader interoperability. For game development and animation, converting to FBX preserves the skeletal rig and animations. For static rendering or 3D printing, OBJ provides a universally compatible mesh. For VTubing and use in VRChat, converting to VRM is the standard workflow. convert.guru simplifies this process, allowing you to instantly transform specialized MMD models into usable assets for your preferred creative suite.
Use Convert.Guru to open and convert your PMX file.
Users also converted MMD, ZIP, VRM, FBX, PRNX, OBJ, RAR, BLEND, SB_, GLB, DAE, PMX2 and XPS files.
If you want to convert PMX file to VRM, PDF, PMD, MMD, DAE, MAX or BLEND, you can use MikuMikuDance or similar software from the "3D Character Model" 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 PMX, try MikuMikuDance or another comparable tool in the "3D Character Model" 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 PMX converter.
