How to convert OBJ to FBX
Need to convert OBJ to FBX? OBJ is a simple, universal static mesh format with basic material references; FBX is best for moving rigged or animated assets between DCC tools. This guide covers exactly what survives the conversion, what you can lose, and the quickest reliable workflow.
What transfers and what you lose
- Materials usually carry across, but re-link textures and check that texture paths and colour space survived the conversion.
- Check units and scale after importing. OBJ and FBX workflows often assume different default units, which is the most common cause of a model arriving far too large or too small.
Recommended workflow
- Open your OBJ file. Import the OBJ file into a tool that reads both formats, such as Blender (free), Cinema 4D, 3ds Max or MeshLab.
- Check scale, units and orientation. Confirm the model is the right size and facing the right way before exporting. Fix the units now rather than in the target application.
- Set up materials for the target. Assign materials and re-link textures so they export cleanly to FBX.
- Export as FBX. Export to FBX using the correct options for moving rigged or animated assets between DCC tools, then re-open the result to confirm geometry, scale and materials are intact.
Frequently asked questions
What is the easiest way to convert OBJ to FBX?
Open the OBJ file in Blender (free), Cinema 4D, 3ds Max or MeshLab, check the scale and materials, then export as FBX. It is free and avoids the quality loss of one-click online converters.
Will I lose anything converting OBJ to FBX?
Materials usually carry across, but re-link textures and check that texture paths and colour space survived the conversion.
Why does my model come in the wrong size?
OBJ and FBX often assume different default units. Set the units explicitly on import and export, then verify the dimensions against a known measurement.
