## What is GLTF Viewer · Convert OBJ/STL?

GLTF Viewer opens .gltf and .glb 3D model files and gives you a complete, professional inspector for the glTF format.

VIEW YOUR MODEL
• Orbit, pan and zoom with smooth touch controls
• Solid, Wireframe, X-ray and Points render modes
• Play back embedded animations: scrub, switch clips, change speed
• Toggle grid, auto-rotate, and 3 lighting/environment presets
• Works with Draco-compressed geometry and KTX2/Basis-compressed textures inside your glTF/GLB
• Handles very large files gracefully: models over 400MB switch to a full data inspector even without a live 3D preview

FULL glTF INSPECTOR
• Scene graph / node structure
• Every mesh, material (PBR values) and texture
• Animation clips and accessor/buffer data
• Raw glTF JSON viewer
• Complete glTF 2.0 validation report with errors, warnings and exact JSON-pointer locations

EXPORT, AR AND MEASURE
These tools require an in-app purchase:
• Export / convert your model to another format: GLB, glTF, OBJ, STL, PLY or USDZ
• View your model in AR, right in your own space, with USDZ Quick Look
• Tap-to-measure real-world distances on the model
• Advanced render modes: Normals, Matcap, UV-checker
• Hi-resolution screenshot capture

Open a file from the Files app, iCloud Drive, Mail, AirDrop or any app's Share Sheet, or tap "Open File" inside GLTF Viewer. No account, no login required.
