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 .vxm part and .vxa clip loads together; export a complete bundle back to disk.

.vxa / .vxa.json Open, Append & Export

Native 24 FPS keyframe animation clips. Open alongside a .vxr rig, append extra clips onto an open rig in one undo step, or export single clips for an existing bundle.

.vxb 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 Import (Voxelize) & Export

Importing polygon meshes converts them into editable voxels. Exporting produces greedy-meshed GLB (standard, single-skin consolidated rig, or lossless meshopt), glTF and Wavefront OBJ. For direct polygon editing without voxelizing, use MeshEdit.

.dae & .mp4 Export

COLLADA (.dae) interchange meshes and offline-sampled H.264 .mp4 videos up to 1080p for turntables, animation clips and bouncing voxel build animations.

Convert VOX or VXM to a rigged GLB in four steps

  1. Open VoxEdit Web and choose Open a project for a .vox or .vxm model, or Open a rig folder for an existing .vxr + .vxm + .vxa directory.
  2. 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.
  3. Preview lighting and shadows in Render view, or check loop seams and foot contacts in Agent studio → Motion tools.
  4. 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.
