glTF / GLB Viewer

• Open .gltf and .glb scenes and see them as intended: useful for checking an export before it goes into a game engine, AR pipeline or web page.

macOS previews photos, PDFs and video. It does not preview 3D models, and glTF is the format 3D on the web, in AR and in game engines actually uses. Download a .glb and your Mac shows you nothing at all.

glTF Viewer renders them properly, with the full physically based material model the format was designed around: base colour, metallic-roughness, normal maps, emissive and embedded textures. Thumbnails show the real model. Quick Look gives you an interactive preview from the Space bar. The viewer app lets you orbit, zoom and inspect.

Both flavours are supported: .gltf, where geometry and textures sit in separate files, and .glb, where everything is packed into one binary. Rendering is native SceneKit, and the file never leaves your machine. There is no account, no cloud processing and no telemetry.

If you work with Blender exports, Sketchfab downloads, AR assets or engine pipelines, this is the missing preview.

Requirements

Universal binary, so it runs on both Intel and Apple Silicon Macs.

• macOS 14 (Sonoma) or later
• Intel Mac or Apple Silicon (M1 or newer)

Installation

Download the file, unzip it, and copy it into your Applications folder. Open it once and it registers the Quick Look handler itself. Instructions are included with the download.
