Online 3D Editor

Online 3D Editor is a free 3D modeling application that runs entirely in the web browser, with an interface and keyboard-driven workflow modeled closely on Blender. There is nothing to install, and files are processed on the user's own device rather than uploaded to a server.

It imports common 3D formats — GLB, glTF, OBJ, STL, FBX, PLY, DAE, 3MF and USD — and covers a full modeling pipeline: mesh editing, sculpting, texture and weight painting, rigging, keyframe animation with a Graph Editor, UV unwrapping, and a library of modifiers such as Boolean, Array, Bevel, Mirror and Remesh. Node-based Shader, Geometry and Compositor editors are included, alongside real-time Eevee/Workbench viewport rendering and Cycles path-traced rendering with HDR lighting.

The site also bundles a set of standalone, client-side utilities: GLB/STL/USDZ optimizers, automatic LOD generation, STL repair and printability checks, an online slicer that turns STL/3MF models into G-code (with print-over-USB support), format converters (including CAD STEP/IGES to GLB/STL), and generators for 3D text, lithophanes, heightmap terrain, SVG-to-3D extrusion and LED neon signs.

Core modeling, importing and the everyday tools are free. An optional Pro upgrade unlocks Cycles rendering, the full sculpt/paint/rig/animation toolset, the node editors, advanced modifiers, and export to FBX, OBJ, STL, PLY and USDZ (GLB and glTF export stay free). Pro is a single one-time payment with no subscription.
