OBJ — Wavefront OBJ 3D Model

OBJ is a widely supported 3D model format from Wavefront: geometry with texture coordinates, read by almost every 3D program.

About the OBJ format

OBJ was developed by Wavefront Technologies in the 1980s. It is a text file listing vertices, texture coordinates, normals and faces; materials and textures live in a separate .mtl file and image files next to it.

Because nearly every 3D program imports OBJ, it is the usual way to move a model between applications. Convert.Online writes the geometry as a single OBJ without the .mtl file, and turns OBJ into STL for printing or GLB for the web.
