OBJ Converter

The OBJ Converter is a browser-based utility that transforms Wavefront OBJ files into other widely used 3D formats. It accepts OBJ and optional MTL files and outputs formats such as STL, GLTF/GLB, FBX, and PLY, enabling cross‑tool workflow without software installation. It is designed for 3D artists, game developers, educators, and engineers who frequently exchange models between modeling, rendering, and printing tools.
Conceptually, the tool parses vertices, normals, texture coordinates, and material references from the OBJ/MTL pair, applies an optional unit scaling, and then re-encodes the data into the chosen target format. It triangulates polygons when needed and can embed textures or reference external files depending on the destination format's capabilities.
Value and use cases include preparing assets for game engines, 3D printing pipelines, or collaboration across teams that rely on different software. Unique differentiators are its in-browser operation, support for multiple target formats, explicit unit handling and scaling, and transparent handling of OBJ/MTL relationships without requiring local software.
Core features include a simple file upload, target format selection, optional unit conversion, optional texture embedding, triangulation support, and a downloadable converted file. Typical workflows are OBJ to STL for printing, OBJ to GLTF for web-based viewing, and OBJ to FBX for exchange with professional pipelines.
