Free online USDZ to USDC converter

Source format: USDZ

USDZ is a packaged 3D file format used for Apple AR workflows and other augmented reality viewers. It is essentially a zip-like archive that bundles a USD scene together with textures and related assets, usually without compression. USDZ files are commonly created by 3D artists, product visualization teams, and AR content creators who need a portable model that can be previewed on iPhone, iPad, and macOS.

Typical use cases include AR product previews, e-commerce visualization, educational models, and sharing 3D scenes that must keep geometry, materials, and textures together in one file.

Target format: USDC

USDC is the binary, compact form of USD (Universal Scene Description). Compared with text-based USD files, USDC is designed for smaller size, faster loading, and efficient interchange in production pipelines. It is widely used in film, animation, VFX, game development, and 3D asset workflows where performance matters.

USDC is useful when you want a USD scene that is easier for software to load and process than a plain-text USD file. It is especially common in pipelines built around Pixar USD, Omniverse, and other DCC tools that support USD.

How to perform the conversion

Converting USDZ to USDC usually means extracting or repackaging the USD scene data from the archive into a binary USD file. The best method depends on whether your USDZ contains a single scene layer or multiple referenced assets.

Option 1: Use a USD-capable desktop tool

1. Install a tool that supports USD import/export, such as Pixar USD tools, Blender with USD support, or a DCC application that can open USDZ.
2. Open the .usdz file in the application.
3. Inspect the scene and confirm that textures and references load correctly.
4. Export or save the scene as USDC using the application’s USD export options, often found under File → Export or File → Save As.
5. Choose .usdc as the output format and save the file.

Option 2: Use Pixar USD command-line tools

If you have the USD utilities installed, you can often unpack or convert the scene with command-line tools. A common workflow is to inspect the archive, then export the scene layer to binary USD. Depending on the toolset version, commands may vary, but the general process is:

1. List or inspect the contents of the USDZ package.
2. Open the root layer from the archive.
3. Save or export it as a binary layer with the .usdc extension.

For example, some pipelines use USD tools to convert a scene layer by opening the source and writing a binary output file such as scene.usdc. If your software supports direct conversion, select the source .usdz and export to .usdc.

Option 3: Use the built-in online converter on 101convert.com

You can convert the file on 101convert.com for free, without installing any software. Upload the .usdz file, choose USDC as the output format, and download the converted file when processing is complete.

Notes on quality, compatibility, or limitations

USDZ and USDC are closely related, so this conversion is usually about changing packaging or encoding, not changing the 3D content itself. In most cases, geometry and materials should remain intact. However, there are important limitations:

• Textures and external assets may need to be extracted or relinked if the source USDZ contains references that your converter does not preserve automatically.
• USDZ is an archive, so converting to USDC may remove the self-contained packaging that makes USDZ convenient for AR sharing.
• USDC is not an AR delivery format by itself; some AR viewers expect USDZ specifically, so a converted USDC file may not open in the same apps.
• Compatibility depends on the tool: not every 3D application can read USDZ and write USDC correctly, especially when the scene uses advanced USD features.
• If the USDZ contains multiple layers or references, the resulting USDC may represent only the main layer unless the conversion tool also preserves the full asset structure.

For best results, use a USD-aware application or the 101convert.com converter when you need a quick, no-install conversion.
