3D Model Viewer

View and spin a 3D model in your browser — STL, OBJ, PLY, GLB or glTF. Nothing is uploaded; it all runs on your device.

Drop a 3D model to view it

.stl · .obj · .ply · .glb · .gltf — the first run loads the 3D viewer once

How to use

  1. Drop a 3D model in, or tap the box to choose one. STL, OBJ, PLY, GLB and glTF all work.
  2. Drag to rotate, scroll to zoom and right-drag to pan. Use the panel to change the background and model colour, toggle wireframe, grid and auto-rotate, switch between smooth and flat shading, or reset the view.
  3. Press Save PNG to download a snapshot of the current view. The info panel shows the triangle and vertex counts and the model’s width, height and depth.

FAQ

Which 3D file formats can I open?

STL, OBJ, PLY, GLB and glTF (.gltf). STL and PLY are common for 3D printing and scanning, OBJ is a widely shared mesh format, and GLB/glTF are the modern web 3D formats. Drop any one of them and it renders right away.

Is my model uploaded anywhere?

No. The file is read and rendered entirely in your browser using WebGL — it never leaves your device, so the viewer works offline and stays private. The 3D engine loads once on first use and is then cached.

Why is my model grey or untextured?

STL, PLY and OBJ files often carry no colour or material, so the viewer shows them in a single model colour you can change in the panel. GLB and glTF models keep their own materials. Single-file glTF without its external textures may also appear plain.
