Free online OBJ to VRML converter

A legacy VRML viewer or visualization system may accept .wrl files but not Wavefront OBJ, so the model needs to be exported in VRML format. VRML can represent scene nodes and transforms, but conversion cannot restore information missing from the OBJ file or its companion files.

What OBJ files contain

Wavefront OBJ is a text-based format used by 3D modeling, sculpting, and rendering applications to exchange geometry. It can store vertices, polygon faces, normals, texture coordinates, and group names; material definitions are commonly referenced in a separate .mtl file, with image textures stored separately.

What VRML is

VRML, commonly VRML97, is a text-based 3D scene format usually saved as .wrl. Its scene graph can describe geometry, transforms, materials, texture references, and interactive elements. It remains useful when a legacy viewer or visualization system specifically requires VRML.

How to convert an OBJ file to VRML

On 101convert.com: Choose the OBJ-to-VRML conversion, select the .obj file, run the conversion, and download the resulting .wrl file. The conversion runs with Blender; the page displays the per-file size limit. The service is free to use without installing software.

On a desktop: Use a converter that supports both OBJ import and VRML97 export, such as 3D Object Converter. Open the OBJ with its associated .mtl and texture images, then export or save the model as VRML97 (.wrl).

Quality and compatibility

OBJ does not specify a standard unit, while VRML uses meters. Check the model's dimensions and scale in the target viewer, and verify its axis orientation. Geometry and UV coordinates can transfer, but material appearance depends on the .mtl definitions and referenced image files being available and supported; missing or incompatible references can leave the model untextured. OBJ does not store animation or a complete scene setup, so those cannot be preserved in conversion. Inspect face orientation, textures, and scale in a VRML viewer after exporting.
