About ModelView
A free, privacy-first 3D model viewer and converter that runs entirely in your browser.
What it does
ModelView lets you preview 3D model files — STL, OBJ, GLB, glTF, PLY, 3MF, FBX, STEP and IGES — directly in your web browser. It also converts between common formats (STEP/IGES → STL, STL → OBJ, and more) with no sign-up and no software to install.
Privacy by design
Every file you open is parsed locally on your own device. Nothing is uploaded to any server — there is no server to upload to. Your models stay yours.
Who runs this site
ModelView is an independent project built and maintained by a solo developer who wanted a fast, no-nonsense way to inspect 3D files without handing them to a cloud service. If you have feedback or run into a bug, the contact page tells you how to reach out.
