Quady3D extension support
View and convert 3D mesh files in Chrome. Local viewing and conversion are free and require no account.
Open a model
Click the Quady3D toolbar icon, then choose a file or drag one into the preview. Try Sample to explore the viewer. Use the expand button for a larger view.
Supported inputs: GLB, self-contained glTF 2.0, OBJ and STL. Files must be no larger than 50 MB, with at most 2 million vertices or triangles.
Inspect and export
Drag to rotate and scroll to zoom. The preview controls include fit, front, top, wireframe, auto-rotate, grid and background. Info shows mesh counts and dimensions. PNG saves a preview image.
Choose GLB, OBJ or STL, then Download. Source scale and orientation are preserved. OBJ and STL contain geometry only. GLB retains supported mesh materials and embedded textures. Animation, rigs and morph targets are not retained. Check printable geometry in a slicer.
Open a model link
Right-click a direct model-file link and choose Preview 3D model with Quady3D. Click the load button to request access to that site's origin. Access is optional; local files work without it. Revoke site access in Chrome's extension settings.
If a file will not open
Compressed glTF and separate material or texture files are unsupported in this release. Export a self-contained, uncompressed GLB or a geometry-only OBJ/STL and try again. Model links must be direct HTTP or HTTPS file URLs; redirects, authentication and cross-origin restrictions can prevent loading. Download the file yourself and open it locally when appropriate.
