Open VOX, VXM, VXR and VXA in your browser.
Inspect, edit, rig and convert MagicaVoxel and VoxEdit by The Sandbox files with no desktop installer and no cloud upload. Every byte stays in your browser tab, ready to export as optimized GLB, native voxel bundles or 1080p MP4 video.
Supported voxel, rig and 3D formats
VoxEdit Web is a Three.js port by Hammy of VoxEdit by The Sandbox, built around native voxel layers, articulated hierarchies and clean game-engine exports.
| Format | Direction | What is preserved & how it works |
|---|---|---|
.vox |
Open & Export | MagicaVoxel voxel models and color palettes. Opens directly in Modeler for layered editing, rigging or clean greedy-meshed GLB export. |
.vxm |
Open & Export | Native layered voxel models from VoxEdit by The Sandbox, preserving named layers, visibility, custom palettes, emissive materials, pivots and runtime display masks. |
.vxr + folder |
Open & Export | Articulated voxel rigs with parent-local bone hierarchies and IK metadata. Open a rig folder (or multi-select companions) so every referenced |
.vxa / .vxa.json |
Open, Append & Export | Native 24 FPS keyframe animation clips. Open alongside a |

Open & Save | 32×32×32 six-face painted voxel blocks supported through Open file and File → Specialist workflows. |
.vxm.json |
Open & Save | VoxEdit Web’s full editable project format: layers, reusable library parts, rigs, all clips, Bézier curve handles, blink intervals and legacy embedded polygon meshes. |
.glb, .gltf, .obj |

Convert VOX or VXM to a rigged GLB in four steps
- Open VoxEdit Web and choose Open a project for a
.voxor.vxmmodel, or Open a rig folder for an existing.vxr+.vxm+.vxadirectory. - Refine layers, palette colors and emissive accents in Model, or switch to Animate to attach reusable parts to a biped, creature or custom rig and keyframe motion on the timeline.
- Preview lighting and shadows in Render view, or check loop seams and foot contacts in Agent studio → Motion tools.
- Choose Export → 3D model / animation (.glb) for an engine-ready asset with shared materials and compact indices, Skinned voxel rig (.glb) for a single-mesh rig, or Compressed 3D model (.glb · meshopt) for smaller web delivery.
Why creators convert and inspect files here
Private, local browser parsing
Files are decoded in memory inside your tab—no upload queue, no server retention and no account wall. Browser-local recovery checkpoints protect active edits across reloads.
Clean greedy-meshed GLB
Exports merge coplanar faces, deduplicate identical vertices and materials, strip constant animation keys at float32 precision, and generate emission atlases only when needed.
Automate imports & exports with AI
In a WebMCP browser, agents can inspect imported rigs, batch-convert clips and verify decoded GLB motion against the source rig. Learn more on the AI Agents page.
Format questions and answers
Are my VOX, VXM and VXR files uploaded to a server?
No. VoxEdit Web parses, edits and exports every file locally in your browser using JavaScript and WebGL 2. Your models and rig bundles never leave your device unless you export and share them yourself.
How do I open a VXR rig with its VXM parts and VXA animations?
Choose Open a rig folder on the start screen (or File → Open rig folder in the editor) and select the folder that holds the .vxr file alongside its referenced .vxm models and .vxa animation clips. You can also multi-select the companion files together in Open a project.
Can I convert a MagicaVoxel VOX or VoxEdit VXM file to GLB online?
Yes. Open the .vox or .vxm file in VoxEdit Web, inspect or rig it if needed, and choose Export → 3D model / animation (.glb) or Compressed 3D model (.glb · meshopt). Exported GLB files merge greedy voxel faces, share geometry and materials, and preserve emissive palette colors.
What happens when I open an OBJ, glTF or GLB mesh?
VoxEdit Web voxelizes imported OBJ, glTF and GLB polygon meshes onto an editable voxel canvas so you can paint, slice or rig them as voxels. If you want to edit polygon vertices, faces and UVs directly without voxelizing, open the file in MeshEdit at meshedit.xyz.
Should I save .vxm.json or native VXM and VXR files?
Save .vxm.json for complete VoxEdit Web round-trips, including Bézier curve handles and blink intervals. Export native .vxm or .vxr bundles (24 FPS .vxa clips) when moving assets back into workflows built around VoxEdit by The Sandbox, and keep backups of original desktop files.
