Drop a .glb or .gltf file below to preview it exactly as it will look on the web — PBR materials, textures and all. The viewer runs three.js locally in your browser, so AI-generated models, game assets and AR content stay private.
GLB embeds geometry, materials and textures in one binary — the viewer renders them with image-based lighting, just like a web or AR runtime would.
Binary GLB and JSON glTF open the same way. Self-contained files preview best; glTF with external buffers needs its sidecar files.
Files are parsed in the browser and never uploaded — safe for unreleased game assets and client work.
Drag a .glb (or self-contained .gltf) into the drop zone, or click to browse.
Orbit around the model and verify textures, roughness and proportions render as intended.
Ready for the web? You're done. Need it printable? Convert GLB to STL with the free converter below.
GLB is the binary form of glTF, the "JPEG of 3D" standardized by the Khronos Group. A single .glb file packs meshes, PBR materials, textures, animations and scene structure, which is why it powers 3D on the web, AR Quick Look alternatives on Android, e-commerce viewers and most AI 3D generators — including Sculpty's own text-to-3D studio.
A .gltf file is JSON that usually references an external .bin buffer and texture images; a .glb bundles everything into one binary file. This viewer opens both, but a .gltf that references external files it cannot reach will show an error — in that case, convert it to a self-contained GLB with the free glTF to GLB converter linked below.
Yes — free and unlimited, with no signup. It is one of Sculpty's free tools alongside the AI text-to-3D studio.
No. The model is parsed and rendered locally with three.js. Nothing leaves your machine.
Plain .gltf files often reference an external .bin buffer and separate texture images. If those sidecar files are missing the browser cannot fetch them. Use a self-contained .glb instead — or pack your file with the free glTF to GLB converter.
The viewer focuses on static inspection of geometry and materials. Animated GLBs load and display in their rest pose.
Yes — Sculpty generates textured GLB models from a text prompt in about a minute, free to try.
Type a prompt, get a textured 3D model in about a minute — then download it as GLB, STL, OBJ, FBX or USDZ.
