What is a PMX file?
A .PMX file is primarily a MikuMikuDance Model File. It contains 3D character model data used in MikuMikuDance (MMD). These files store 3D meshes, textures, bones, and physics data. MikuMikuDance is a popular animation program originally created to animate Vocaloid characters. The .PMX format is the modern successor to the older .PMD format.
In rare cases, a .PMX file can also be a PrintMaster Project File created by Broderbund. Because .PMX has multiple possible meanings, we recommend using viewer.online/pmx to identify the actual format of your file.
How to open PMX files?
The standard way to open a .PMX 3D model is to use MikuMikuDance. Creators also use PMXEditor to modify and rig these models. If you use standard 3D software like Blender, you can install a community plugin like mmd_tools to import and edit .PMX files.
If your file is a PrintMaster Project File, you will need PrintMaster software to open and print the layout.
Convert PMX files
If you want to use a .PMX 3D model in different software like Unity, Maya, or Unreal Engine, you should convert it. You can use convert.guru to easily convert .PMX files to more common 3D formats like .FBX, .OBJ, or .DAE.
Summary
viewer.online/pmx analyzes .PMX files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. viewer.online/pmx directly opens and previews .PMX files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
