25 June 20266 min

Microsoft 3D Viewer not enough? The 5 best browser-based alternatives in 2026 for viewing and sharing 3D files online: no Windows required.

Microsoft 3D Viewer comes pre-installed on Windows 10 and 11. It's a convenient way to quickly open a GLB or OBJ file received by email. But the moment you need to share a model with a client, open a STEP file, or view on a Mac — you've hit its ceiling.

Microsoft 3D Viewer limitations

Desktop only: cannot share a link to a 3D model
Windows only: no Mac, Linux, or mobile support
Limited formats: GLB, OBJ, FBX, STL, 3MF — no STEP or IGES
No sharing: recipient must have the file on their computer
