VOX Viewer — Open MagicaVoxel Files Online
Open MagicaVoxel .vox models with their palette colours and convert them to a mesh for any engine.
Your VOX file is read and rendered entirely by your own browser. It is never uploaded to A23D, never stored, and never seen by anyone but you.
How to open a VOX file
No account, no plugin, no upload. Three steps and your model is on screen.
Drop in your file
Drag the .vox onto the viewer, or click to browse. If the model references separate material or texture files, drop the whole folder or a .zip so everything resolves.
Inspect the scene
Orbit, pan and zoom to look around. The inspector lists every mesh in the hierarchy with its triangle count, and reports the bounding box so you can sanity-check scale.
Convert or capture
Save a PNG of the viewport, or download the model converted to GLB, OBJ, STL, PLY or USDZ — all without the file leaving your browser.
What is a VOX file?
VOX is the file format of MagicaVoxel, the free voxel editor by ephtracy that became the default tool for voxel art. If you have seen the blocky, brightly coloured models common in indie games and isometric illustration, they were very likely built in MagicaVoxel and saved as .vox.
A voxel is a volume element — a pixel with depth. Rather than describing a surface with triangles, a VOX file stores a three-dimensional grid and records which cells are filled and what colour each one is. It is closer in spirit to a 3D bitmap than to a conventional mesh.
The format is a compact binary chunk structure. It stores the model dimensions, a list of filled voxels as x, y, z and palette index, and a 256-colour palette. Colour is always an index into that palette, which is why voxel art has its characteristic limited, deliberate colour schemes.
A single model is capped at 256 × 256 × 256 voxels. Larger scenes are built from multiple models arranged in a world, and newer versions of the format store several models with transform nodes in one file.
To display voxels on a GPU they must become triangles, so this viewer builds a mesh from the volume — each filled voxel becomes a coloured box. That is exactly what you need when moving voxel art into a conventional engine, and you can export the result as GLB, OBJ or STL for printing.

VOX viewer FAQs
The questions we get asked most about opening VOX files.
Do I need MagicaVoxel installed?
No. The .vox file is read directly in your browser, so you can inspect or convert voxel models without installing anything.
Is my .vox uploaded anywhere?
No. It is parsed and rendered locally. Nothing is transmitted to A23D or stored.
Can I convert VOX to OBJ or GLB?
Yes, and it is the usual reason to come here. The voxel volume is turned into a mesh, which you can then export as GLB, OBJ, STL, PLY or USDZ — that is how voxel art gets into Unity, Unreal, Blender or a 3D printer.
Why does my model have so many triangles?
Every filled voxel becomes a box, so a dense model produces a very large triangle count. For game use you would normally run the result through a mesh optimiser or use a greedy-meshing exporter to merge coplanar faces.
Why are my colours slightly different?
VOX colours are indices into a 256-entry palette stored in the file. The palette is read and applied as vertex colours. Rendering differences come from lighting and tone mapping rather than the colour data itself.
Is there a size limit on VOX models?
The format itself caps a single model at 256 x 256 x 256 voxels. Larger scenes are assembled from several models, and files containing multiple models are handled here.
