About PMX files
The .PMX file extension primarily represents a 3D character model file utilized by MikuMikuDance (MMD), a popular freeware 3D animation program. These files store polygon meshes, texture paths, skeletal bones, physics data, and morph targets for 3D avatars. Secondarily, .PMX acts as a proprietary project layout file created by PrintMaster, an older desktop publishing application developed by Broderbund. The most significant disadvantage of the .PMX 3D format is its closed, hyper-specific ecosystem. Native .PMX models cannot be directly loaded into modern game engines like Unity or Unreal Engine or viewed in standard web browsers. Furthermore, much of the file's internal metadata, bone structures, and material names are encoded in Japanese text using Shift-JIS. When imported into Western software environments, this frequently results in "Mojibake" (corrupted, unreadable text) that breaks rigging scripts and texture links. The PrintMaster variation is equally restrictive, requiring paid, legacy software to view basic graphic layouts. To properly utilize these files in standard production pipelines, conversion is mandatory. For 3D workflows, convert .PMX to FBX to retain bone rigs and basic materials for animation, or to OBJ for static meshes (note that OBJ will strip out physics and skeletal rigging). For PrintMaster desktop publishing files, convert to PDF for accurate archiving and printing, or JPG for quick web distribution. Drag and drop your file here to analyze and convert it securely right in your browser - free, online, and without installing software.

The PMX 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 PMX converter.
