How to convert USDZ to GLB
Need to convert USDZ to GLB? USDZ packages meshes and PBR materials for Apple's AR Quick Look; GLB is best for web, real-time and AR delivery. 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.
- Animation and rigs can carry across, but always play back the result in the target tool, as bone and frame-rate handling differs between formats.
- Check units and scale after importing. USDZ and GLB 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 USDZ file. Import the USDZ file into a tool that reads both formats, such as Apple's Reality Converter, usdzconvert, or Blender's USD export.
- 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 or rebuild PBR materials (base colour, roughness, metallic, normal) so they survive as GLB.
- Export as GLB. Export to GLB using the correct options for web, real-time and AR delivery, then re-open the result to confirm geometry, scale and materials are intact.
Frequently asked questions
What is the easiest way to convert USDZ to GLB?
Open the USDZ file in Apple's Reality Converter, usdzconvert, or Blender's USD export, check the scale and materials, then export as GLB. It is free and avoids the quality loss of one-click online converters.
Will I lose anything converting USDZ to GLB?
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?
USDZ and GLB often assume different default units. Set the units explicitly on import and export, then verify the dimensions against a known measurement.
