About 3D Model Viewer

This free 3D model viewer online opens STL, OBJ, GLB, GLTF, PLY, 3MF, FBX and DAE files in your browser. Drag to turn the model, scroll to zoom, reset the view or switch to wireframe. The page shows the triangle count and the size of the model. Your file is never uploaded.

It is useful for checking a part before 3D printing, or a model before you put it on a website. You can save a PNG picture of the model and convert between STL, OBJ and GLB. GLTF files that need separate texture or bin files may open without their textures.

How to use 3D Model Viewer

  1. Select your 3D model file.
  2. Drag to turn it and scroll to zoom in or out.
  3. Save a PNG picture or convert to STL, OBJ or GLB.

Frequently asked questions

How do I open an STL file without software?

Select the STL file on this page and it opens in your browser. Drag to turn it and scroll to zoom.

Can I convert OBJ to STL for 3D printing?

Yes. Open the OBJ file and save it as STL. You can also convert between STL, OBJ and GLB in any direction.

Why does my GLTF model have no textures?

Some GLTF files keep their textures and data in separate files. If those files are not included, the model may open without textures. A GLB file keeps everything in one file.

Is my model uploaded?

No. The model is opened inside your browser and stays on your device.
