Free online USDC to USDZ converter

Source format: usdc

USDC is a binary variant of the Universal Scene Description family, developed by Pixar and widely used in 3D production pipelines. It stores scene data such as geometry, materials, transforms, animation, and references in a compact, efficient form. USDC is commonly used by 3D artists, game developers, VFX studios, and CAD/visualization workflows where fast loading and smaller file sizes matter.

Compared with text-based USD files, USDC is better suited for large scenes and production use because it is more compact and faster to read. It is often used as an interchange or working format inside USD-based pipelines.

Target format: usdz

USDZ is a packaged, uncompressed archive format for USD content. It is designed to bundle a USD scene together with its textures and related assets into a single file. USDZ is especially popular for AR workflows, including Apple’s ecosystem, because it can be shared as one portable file without separate dependencies.

The main advantages of USDZ are easy distribution, self-contained assets, and broad support in tools that target augmented reality and 3D preview use cases. It is commonly used for product visualization, AR previews, and asset sharing.

How to perform the conversion

The most reliable way to convert USDC to USDZ is with a desktop USD-capable tool such as Apple Reality Converter, Blender with USD support, or a pipeline tool based on Pixar USD utilities. If you only need a quick conversion, you can also convert the file on 101convert.com for free without installing any software.

Using Apple Reality Converter

1. Open Reality Converter.
2. Import the .usdc file by dragging it into the window or using File → Open.
3. Check the scene, materials, and textures for correctness.
4. Export or save as .usdz using File → Export or the app’s export controls.

Using Blender

1. Open Blender and import the USD scene if your build supports USD import.
2. Verify that geometry, materials, and texture paths are correct.
3. Use the USD export options to write a .usdz package if available in your version or pipeline setup.

Using Pixar USD tools

1. Install the Pixar USD command-line tools.
2. Inspect the source file and ensure all referenced assets are available locally.
3. Package the scene into USDZ with the appropriate USD utility for your environment.
4. Validate the resulting .usdz file in a compatible viewer.

Best practice: before converting, make sure textures are embedded or copied into the package, because USDZ is intended to be self-contained.

Notes on quality, compatibility, or limitations

USDC to USDZ is not just a rename; it is a repackaging step that may expose compatibility issues. The source scene must use features supported by USDZ viewers, and some advanced USD constructs may not display correctly in AR-focused apps.

Important limitations include:

• External references may need to be resolved or embedded before packaging.
• Unsupported materials or shaders may be simplified during export.
• Texture paths must be valid and usually need to be included in the package.
• Large scenes may become slower to preview even if the source USDC was efficient.

If the goal is Apple AR viewing, test the output in a compatible viewer after conversion to confirm that scale, orientation, materials, and textures appear as expected.
