Free Online OBJ Viewer

View any OBJ file in 3D. Place it in AR on iPhone or Android. Works in your browser.

OBJ is the standard export format from Blender, Maya, Cinema 4D, and most 3D tools. Whether you're sharing a model for review or checking a downloaded asset before using it in your project, you need a quick way to see it without opening a heavy application.

GeometryViewer opens OBJ files directly in your browser — no install, no upload. Drag the file in and rotate with your mouse or finger. On mobile, place it in Augmented Reality to see it at real scale in your environment.

Blue material is applied automatically when no MTL file is present, giving every model a clean, consistent look.
