OBJ viewer
OBJ files are plain text, so they're easy to make and easy to break. Open one here to confirm the geometry is intact before importing it into a bigger scene.
Choose a file to see its details here. Nothing is uploaded: everything runs in your browser.
How to use the obj viewer

Tips for better results
- The .mtl and texture files aren't loaded, so expect a grey model.
- Very large OBJs can take a few seconds to parse.
Common OBJ problems
- Grey model: the .mtl file and textures weren't included, which is normal when opening only the .obj.
- Sideways model: different apps use Y-up or Z-up. Rotate it in your target app.
- Huge file: OBJ is text. Converting to GLB usually shrinks it a lot.
- Faceted look: the OBJ has no normals. Most apps can recalculate them.
