OBJ to VOX Converter
Turn your OBJ 3D model into MagicaVoxel VOX voxels. Choose the detail level and download a .vox file for your next project.
Upload your OBJ model
Up to 50 MB · Surface voxelization · Direct .vox download
Higher values add detail and increase processing time. Thin features may disappear at lower resolutions.
Convert OBJ meshes to MagicaVoxel VOX
Wavefront OBJ stores polygon mesh geometry and may contain vertex colors. This converter accepts standalone OBJ files. External MTL files and textures are not loaded; export a self-contained GLB when you need textured colors.
Create a colored .vox model for MagicaVoxel and voxel editors that support VOX. Mesh surfaces become a voxel grid with a palette of up to 255 colors.
Choose VOX to edit your converted model in MagicaVoxel. The download contains one voxel model and its color palette, ready for voxel sculpting and scene building.
VOX uses a limited palette, so models with more than 255 sampled colors are reduced to the most frequent colors and their nearest matches. Meshes are flattened into a single voxel model; animation and scene hierarchy are not retained.
Set voxel detail
Pick a resolution between 8 and 64. Higher detail creates more occupied cells.
Download VOX
Convert the mesh and save your .vox file for a compatible editor or pipeline.
Choose a voxel file format
Use VOX for MagicaVoxel, QB for Qubicle interchange, BINVOX for occupancy grids, or XYZRGB for colored coordinate data.
OBJ to VOX FAQ
How do I convert OBJ to VOX?
Upload a .obj mesh up to 50 MB, set a voxel resolution from 8 to 64, and select Convert to VOX. When processing finishes, download the .vox file. Conversion runs on the backend without a separate desktop converter.
What is a VOX file used for?
Choose VOX to edit your converted model in MagicaVoxel. The download contains one voxel model and its color palette, ready for voxel sculpting and scene building.
Will colors and textures be preserved?
The converter samples available vertex colors and embedded GLB textures. VOX reduces these samples to a palette of up to 255 colors. Standalone OBJ uploads do not include external MTL files or texture images. Transparency is not preserved.
Does the converter create solid or surface voxels?
It voxelizes mesh surfaces rather than filling the interior. The output uses a Z-up voxel grid and does not retain the source model’s units, rigging, animation, or object hierarchy. Fine details depend on your resolution.
What model limits apply?
Upload a nonempty file up to 50 MB with no more than 250,000 mesh faces, 500,000 vertices, and 256 scene instances. Very complex models may reach the 90-second conversion limit. Simplify the mesh or lower the resolution if conversion fails.
Can I turn the same 3D object into a LEGO design?
Yes. Try the GLB to LEGO converter to create a LEGO-compatible model from a 3D object. Export an OBJ as a self-contained GLB first. You can also start a brick design from an image or a text prompt using BrickBuilder AI.
