Online voxel editor
A full 3D voxel editor - runs in your browser.
A complete voxel editor in the browser. Build models from scratch with proper drawing tools, animate frame by frame, and export to game-ready GLB or pixel art sprite sheet. WebGL via Three.js, no install, autosaved in your browser. Pair it with the AI generator if you want a head start instead of starting from a blank grid.
How it works
Open, build, export.
Pick a tool
Box, Line, Paint, Place, Rect, Eyedropper, Voxel Fill, Remove. Each works in 3D with smart plane inference.
Build and animate
Lay down voxels, paint colors, add frames for animations. Undo/redo for everything. Camera orbit, zoom, fly mode.
Export
Animated GLB for 3D engines, pixel art sprite sheet for 2D engines. Or publish to the community gallery.
Features
A real editor, not a toy.
-
Eight drawing tools
Box, Line, Paint, Place, Rect, Eyedropper, Voxel Fill, Remove. Each one works in 3D space - click on a face, the tool infers the right plane.
-
Multi-frame animations
Animations are stacks of frames. Edit each frame in place, scrub through, replay live in the editor.
-
Undo / redo for everything
Every voxel placement, paint stroke, palette change is reversible. History persists during the session.
-
Smart camera
Orbit by default, fly mode for power users, voxel-aligned framing on demand. Zoom is pixel-aligned so the model never goes blurry.
-
Greedy-meshed rendering
The render uses a greedy mesher in pure JS - same logic as the GLB export - so the editor preview looks identical to your final asset.
-
Local autosave
Your work is autosaved to localStorage as you go. No login, no upload, no waiting.
Examples
Open the gallery
Browse community-built models.
Every model in the gallery was built with this editor - sometimes from scratch, sometimes built on top of an AI starting point. Each one is downloadable, browsable in 3D, and exportable.
FAQ
Common questions.
Is the voxel editor free?
Yes. The full editor - every drawing tool, undo/redo, the camera, GLB and sprite sheet export - is free. Credits are only used by the AI generation features (text-to-voxel, add animation), not by manual editing.
Do I need to install anything?
No. The editor runs entirely in the browser using WebGL via Three.js. Works on Chrome, Firefox, Safari, Edge. No download, no plugin, no Blender, no MagicaVoxel.
What grid size does it support?
The editor uses a 64×64×64 grid. AI-generated content targets 32×32×32 by default but the canvas is large enough to scale up. Imported 3D models can fill the full 64³ box.
Which drawing tools are included?
Box, Line, Paint, Place, Rect, Eyedropper, Voxel Fill, Remove. Each works in 3D - pick a tool, click in the scene, and place voxels along the inferred plane.
Can I animate frame by frame?
Yes. Animations are sequences of frames; you edit each frame directly in the editor with the same tools, then play back to verify timing. AI generation can also produce animations from a prompt.
How do I save my work?
Saves are persisted in localStorage automatically (no signup needed). With an account, you can also publish to the community gallery to keep them on the server.
Can I export the model?
Yes - animated GLB (glTF binary, ready for Three.js, Unity, Godot, Blender) or pixel art sprite sheet PNG (8 directions, 4 isos, top, bottom).
