Next3D Viewer

Next3D Viewer is a free online 3D model viewer from Next3D, built for creators who need a fast way to open and inspect 3D files without installing heavy modeling software. Users can upload a local model file, preview it in an interactive WebGL viewport, rotate, zoom, pan, reset the camera, and review the asset before using it in a game, web app, ecommerce page, AR/VR scene, product prototype, or creative pipeline.

The viewer supports common 3D formats such as GLB, GLTF, OBJ, FBX, STL, PLY, DAE, and 3MF. It is useful for validating generated 3D models, downloaded assets, product visualization files, 3D printing drafts, and web-ready GLB files before sharing or converting them. The strongest angle is a free, browser-based, privacy-first 3D file viewer for everyday asset inspection.
