Browser-local workflow

How this tool works

  1. Step 1

    VOX

    Choose a VOX 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.

Preserved

  • Geometry

Lost

  • Vertex colors
  • Scene hierarchy
  • Units and scale

Direct answer

What is preserved when converting VOX to 3MF?

This converter processes the VOX file locally in your browser and downloads the converted 3MF file. Geometry is retained by the current loader and writer. Vertex colors, scene hierarchy, and units and scale are not included in the downloaded file.

Before you convert

VOX 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 VOX to 3MF
DataResultWhat this implementation does
GeometryPreservedThe custom writer creates one triangle-mesh object from world-space geometry.
MaterialsNot in sourceVOX does not define materials to carry into 3MF.
TexturesNot in sourceVOX does not define textures to carry into 3MF.
Vertex colorsNot exported3MF output from this tool does not store vertex colors.
AnimationNot in sourceVOX does not define animation to carry into 3MF.
Scene hierarchyNot exported3MF output from this tool does not store scene hierarchy.
Units and scaleNot exportedThe VOX format can contain this data, but the current single-file loader does not retain it for conversion.

Verify after export

  • Confirm scale and units when opening the 3MF file in the destination application.

Why choose this VOX to 3MF converter

Local VOX decoding

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

VOX to 3MF data report

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

3MF output checks

Vertex colors is lost; 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 VOX to 3MF online

  1. 01

    Upload your VOX file

    Drag and drop the file into the converter, or click Upload. VOX 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 VOX file format

MagicaVoxel

The .vox format stores models as a grid of colored voxels plus a palette. It is the native format of MagicaVoxel, the most popular free voxel editor, used widely for stylized game art.

When converted to mesh formats, each voxel becomes cube geometry with its palette color preserved as vertex colors.

Format reference: MagicaVoxel VOX format description

Strengths

  • Compact voxel grid encoding
  • Palette colors preserved
  • Perfect for stylized game art

Commonly used for

  • Voxel art and stylized games
  • MagicaVoxel project exchange
  • Voxel-to-mesh conversion

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 VOX model file uploaded to a server?

The selected VOX 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 VOX 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 VOX 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?

VOX 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.

How are voxels turned into a 3D mesh?

Each solid voxel is meshed as cube faces with its palette color stored as vertex colors, so the converted GLB/OBJ keeps the voxel look. Interior faces between neighboring voxels are removed to keep the mesh lean.

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.
