Voxel Forge

Load a GLB, GLTF, FBX, or saved voxel JSON, voxelize models entirely in the browser, inspect the result in 3D, and export sparse palette-indexed voxel data or a voxel GLB.

Drop a model file or a model bundle here

For textured FBX or GLTF, include the sidecar texture files too, upload a ZIP bundle with everything together, or reopen a saved voxel JSON document.

Model URL

Remote URLs can point to `.json`, `.glb`, `.gltf`, `.fbx`, `blob:`, or `data:` sources.

Choose a local model or saved voxel JSON file, or paste a remote model or voxel JSON URL.

Output name

Mirror across X for symmetry Surface only (skip solid interior fill)

The converter preserves aspect ratio, returns a sparse voxel list, and uses 0-based palette indices in the output.

Blank scene

Editor

Add, select, move, rotate, paint, erase, and extrude voxels

Camera mode

Edge Enhancement

Boost silhouette readability in the viewport and optional GLB export with a controllable outline shell.

Convert a model or start a blank grid to begin editing voxels.

3D to voxel

Upload a model and inspect the voxel volume live.

The preview uses the sparse voxel output directly, with deterministic palette colors and the same centered grid dimensions reported in the exported JSON and GLB.

Saved Builds

Save the current voxel document as JSON in this browser's local IndexedDB and reopen your saved builds without downloading files first.

Export

Download the sparse voxel payload exactly as generated by the browser-side converter, export the visible voxel shell as a GLB mesh, or build Mixamo-friendly FBX and OBJ packages with a generated texture atlas.
