Convert images to voxel art
Turn a PNG, JPG or WebP into a flat voxel picture up to 1024 voxels across, then edit it, build on it or save it as .vox.
How it works
Open the file
Open the editor and choose Main menu → Import 3D Model or Image…, or drop the file on the canvas.
Pick the size
Set the longest edge in voxels, up to 1024. The voxels appear on the canvas as you move the slider, and a model bigger than the canvas grows it to fit.
Edit and save
Edit the voxels with every VoxiGen tool, then save as .vox for MagicaVoxel or as .vxb, free and without an account.
Image files
- The picture becomes one voxel deep and keeps its proportions.
- Set the size to the image's longest side in pixels for one voxel per pixel, which suits pixel art.
- Up to 1024 voxels across; the canvas grows to fit.
What to expect
| Size | Up to 1024 voxels on the longest side |
|---|---|
| Colours | Mapped into a palette of up to 256 colours |
| Account | None needed to import, edit or save .vox and .vxb files |
| Price | Free. GLB, glTF, OBJ and STL export come with the Founder licence, $29.99 once |
| .vox files | Up to 256 voxels per side, the format's own limit; larger models save as .vxb |
| Browser | A recent desktop Chrome, Edge or Safari with WebGPU |
Questions
Can I turn a picture into a 3D model?
This converter makes a flat voxel picture. For a 3D model from a picture, Build (AI) uses it as a reference and makes an editable voxel model; it runs on prepaid credits.
Is the converter free?
Yes. Importing, editing and saving as .vox or .vxb are free and need no account. Exporting back to a mesh (GLB, glTF, OBJ, STL) comes with the one-time $29.99 Founder licence.
Can I get a .vox file for MagicaVoxel?
Yes, choose .vox in the Save dialog. A .vox file holds up to 256 voxels per side, so keep the longest edge at 256 or less, or save larger models as .vxb.
