STL Viewer
Open STL files online and inspect them in 3D. Upload an STL, OBJ, FBX, or DAE model to orbit, zoom, and check it before you print.
View STL files online in 3D
Upload an STL and look at it in 3D right in your browser: orbit, zoom, and check every side before you send it to the printer. It also opens OBJ, FBX, and DAE models, and gives you a web-ready GLB copy you can download.
How to view an STL file
- Upload your .stl (or .obj, .fbx, .dae) file.
- Run it.
- The model opens in the 3D viewer. Drag to orbit, scroll to zoom.
Features
- No software to install. Open STL files on any computer, including ones without a slicer or CAD app.
- Four formats. STL, OBJ, FBX, and DAE all open.
- Check before you print. Spot missing parts, wrong orientation, or the wrong file before wasting filament.
- GLB copy included. The viewer copy is a GLB you can download for the web, AR, or presentations.
FAQ
How do I open an STL file without software?
Upload it here and run it. The model opens in a 3D viewer in your browser, with nothing to install.
Which file types can I view?
STL, OBJ, FBX, and DAE.
Can I edit the model here?
The viewer is for looking. To change the file, convert it with STL to OBJ and edit it in a 3D app, or fix broken geometry with STL Repair.
Why does my model look grey?
STL files store shape only, with no colour. That is normal, and it is exactly what your slicer will see.
