Browser-local workflow

How this tool works

  1. Step 1

    USDZ

    Choose a USDZ file from this device.

  2. Step 2

    Browser-local conversion

    The supported geometry is converted in this browser.

  3. Step 3

    3MF

    Download the 3MF result when conversion is complete.

Direct answer

What is preserved when converting USDZ to 3MF?

This converter processes the USDZ file locally in your browser and downloads the converted 3MF file. Geometry is retained by the current loader and writer. Units and scale uses a supported subset. Materials, textures, vertex colors, animation, and scene hierarchy are not included in the downloaded file.

Before you convert

USDZ to 3MF compatibility

These results describe Modelfy's current browser loader and exporter, not every feature allowed by the file specifications.

Data preserved, limited, or lost when converting USDZ to 3MF
DataResultWhat this implementation does
GeometryPreservedThe custom writer creates one triangle-mesh object from world-space geometry.
MaterialsNot exported3MF output from this tool does not store materials.
TexturesNot exported3MF output from this tool does not store textures.
Vertex colorsNot exportedThe USDZ format can contain this data, but the current single-file loader does not retain it for conversion.
AnimationNot exportedThe USDZ format can contain this data, but the current single-file loader does not retain it for conversion.
Scene hierarchyNot exported3MF output from this tool does not store scene hierarchy.
Units and scaleLimitedASCII USDA-based archives preserve metersPerUnit; archives without stage metadata use the OpenUSD centimeter fallback.

Verify after export

  • Compare material colors and textures with the browser preview before using the result in production.
  • Confirm that a static model is acceptable; animation is not exported.

Why choose this USDZ to 3MF converter

Local USDZ decoding

The selected USDZ model file is decoded and rewritten as 3MF on your device; the model file is not uploaded to Modelfy.

USDZ to 3MF data report

The compatibility table identifies geometry as preserved by this loader and writer.

3MF output checks

Units and scale is limited; review the implementation detail and verify the downloaded file in your destination tool.

Preview before export

Inspect the browser preview before converting, then use the post-export checklist to confirm the 3MF result.

How to convert USDZ to 3MF online

  1. 01

    Upload your USDZ file

    Drag and drop the file into the converter, or click Upload. USDZ inputs up to 25 MB are processed locally.

  2. 02

    Convert to 3MF

    Preview the model in 3D, then click Convert. The conversion runs locally in the browser; processing time depends on model complexity and device resources.

  3. 03

    Download the 3MF file

    Your 3MF file downloads straight to your device, ready for the next tool in your pipeline.

About the USDZ file format

Universal Scene Description (zipped)

USDZ packages Pixar’s Universal Scene Description into a single uncompressed ZIP archive. Apple adopted it as the native AR format for iOS: Safari, Messages, and Mail open USDZ files directly in AR Quick Look.

For e-commerce and product visualization, shipping a USDZ next to a GLB covers both Android (Scene Viewer) and iOS (Quick Look) AR experiences.

Format reference: Alliance for OpenUSD USDZ specification

Strengths

  • Native AR support on iPhone and iPad
  • Single-file scene with materials
  • Backed by Pixar’s USD ecosystem

Commonly used for

  • iOS AR Quick Look experiences
  • E-commerce product AR
  • USD pipeline delivery

About the 3MF file format

3D Manufacturing Format

3MF was created by the 3MF Consortium (Microsoft, HP, Prusa, Ultimaker, and others) as the successor to STL for additive manufacturing. It is a ZIP-based container holding an XML mesh description with real units, colors, materials, and printer metadata.

Modern slicers like PrusaSlicer, Bambu Studio, and Cura prefer 3MF because a single file can carry the full print project.

Format reference: 3MF Consortium core specification

Strengths

  • Real units and manifold guarantees
  • Color and material support
  • Native format of modern slicers

Commonly used for

  • 3D print project exchange
  • Color/multi-material printing
  • Slicer-ready model delivery

Frequently asked questions

Is my USDZ model file uploaded to a server?

The selected USDZ model file is processed by the browser and is not uploaded to Modelfy. Website code and static assets still load over the network like a normal web page.

Will I lose quality converting USDZ to 3MF?

Mesh geometry is preserved as closely as the 3MF format allows. The target format may triangulate geometry or drop unsupported features such as animations, materials, textures, or scene hierarchy.

Is the USDZ to 3MF converter free to use?

Yes. The browser viewer, converter, and local 3D text tool require no account and add no watermark. Input limits vary by format, up to 50 MB; AI model generation is a separate credit-based product.

What is the maximum file size?

USDZ inputs up to 25 MB are accepted. The format-specific limit keeps browser-local parsing bounded; actual processing also depends on available memory, model complexity, and device performance.

Why can’t some USDZ files be opened in the browser?

USDZ archives can contain ASCII (.usda) or binary crate (.usdc) data. Browsers can parse the ASCII variant, but binary USDC (which many Apple tools export) has no JavaScript parser yet. If your file fails, convert from the original GLB instead.

Is 3MF better than STL for printing?

3MF stores explicit units, avoids the leaky triangle-soup pitfalls of STL, and can embed colors and print settings, so most modern slicers recommend it. Converted files from this tool use millimeter units.

AI 3D generation

From a single image to a production-ready 3D model

These browser tools stay free for viewing and converting files you already have. When the model does not exist yet, Modelfy generates a textured mesh from one reference image — the first one is free.
