Quady3D — 3D Viewer & Converter

Free STL, GLB, glTF and OBJ viewer. Inspect 3D models offline, convert files, and create new assets with Quady3D.

Open a 3D model in seconds. Quady3D is a free 3D model viewer and converter for Chrome, built for game creators, designers and 3D printing enthusiasts. Click the Chrome toolbar icon to view local STL, GLB, self-contained glTF and OBJ files in a compact popup, without uploading them or creating an account. Expand to a full tab when you need more room. Rotate, zoom, switch to wireframe, inspect mesh counts and dimensions, or save a PNG snapshot of your model. Convert your model to GLB, OBJ or binary STL. Source scale and orientation are preserved. OBJ and STL exports contain geometry only. GLB exports include supported mesh materials and embedded textures. Conversion does not retain animation, rigs or morph targets. Check printable geometry in a slicer. Find a direct 3D file link on a website? Right-click it and choose “Preview 3D model with Quady3D.” Access to that site is requested only when you choose to load the model. Ready to create something new? Open Quady3D to generate a new 3D asset from an image or text, or explore AI texture tools. AI services on the website use a separate account and credits. Local viewing and conversion are free. Local files stay on your device. No browsing-history collection, model uploads, or extension analytics. The only saved preference is your export format. Website links include campaign parameters; website privacy terms apply when you visit Quady3D. Supported input: GLB, glTF 2.0 with embedded resources, OBJ, STL. Maximum 50 MB and 2 million vertices/triangles. Compressed glTF assets and separate OBJ material/texture packages are not supported in this release. Operated by Quady3D AI.
