What is it? 3D Model Viewer displays STL, OBJ, PLY, 3MF, GLB and glTF models in the browser with orbit, zoom and auto-fit, so you can inspect a model before downloading or printing it.
TL;DR: Open STL, OBJ, PLY, 3MF and GLB/glTF 3D models in your browser — drop one in to orbit and inspect it, then measure, annotate, section, explode or screenshot from the toolbar. Free with no sign-in; everything renders locally, so your model never leaves your device.
How to use
- Drop an STL, OBJ (with its .mtl and textures), PLY, 3MF, GLB or glTF file — or click Try a sample to load a built-in model. Nothing is uploaded.
- Orbit and zoom to inspect it — the page shows body count, triangle count and bounding box (model units).
- Use the toolbar to measure distance and angle, annotate, section, explode and screenshot the model — share or embed the view straight from the toolbar.
FAQ
Can it measure?
Yes — use Distance / Angle in the toolbar. For bounding box, surface area and volume, open 3D Model Analysis.
Is it private?
Yes — the model is rendered locally and never uploaded.
Does it support FBX files?
No — FBX is a closed container format. Convert it to GLB first (3D Format Converter), then open the GLB here.
Can I edit or repair the model here?
No — the viewer is read-only. Use Mesh Doctor for repair, and 3D Model Analysis for surface area and volume.
Which file formats does it open?
STL (binary and ASCII), OBJ with its .mtl and textures, PLY, 3MF, GLB and glTF. STEP and IGES have their own viewers; FBX is not supported — convert it to GLB first with 3D Format Converter.
Is there a file size limit?
There is no upload cap because nothing is uploaded — parsing and rendering run in your browser, so the practical limit is your device's memory. Very large models may be slow on low-end devices.
Can I view OBJ files with materials and textures?
Yes — drop the .obj, its .mtl and the texture files together and the viewer assembles them. Without the .mtl the mesh still loads in a neutral material.
Does it show model statistics?
Yes — body count, triangle count and the bounding box in model units appear once the model loads. For surface area and volume, open 3D Model Analysis.
Can I share or embed the model?
Yes — the toolbar includes screenshot, share and embed, so a reviewer can open the same model in their browser without installing anything.
