Getting started
How to use the 3D model viewer
Load a model
Drag in a .glb or .gltf file, or start from one of the built-in samples. Files are processed locally and never uploaded.
Set the scene
Pick an HDR environment, tweak the lighting, choose a background colour, and optionally switch on GPU path tracing for photorealistic results.
Export a screenshot
Choose an aspect ratio — Stories, square, wide banner — and download a high-resolution PNG or JPEG ready for social or your portfolio.
F.A.Q
Frequently asked questions
No. The viewer runs entirely in your browser using WebGL. Your .glb, .gltf and HDR files never leave your device, which makes it safe for unreleased or client work.
Both are the same glTF 3D format. A .gltf file is JSON that references external textures and geometry, while a .glb file packs everything — meshes, textures and materials — into a single binary file. The viewer supports both.
You can export 16:9 (1920×1080), 1:1 and 4:5 for Instagram, 9:16 for Stories and Reels, 21:9 ultrawide, a 1200×630 Open Graph card for Facebook and LinkedIn, and a 1024×1024 square.
Path tracing simulates real light bounces for soft shadows, accurate reflections and realistic lighting. It accumulates samples progressively, so the image refines over a few seconds into a noise-free render you can export.
Yes, it is completely free with no sign-up required and no watermark on exported screenshots.
