Free 3D file converter

Convert between GLB, GLTF, OBJ, and STL entirely in your browser. Files never leave your device.

Honest scope
  • GLB ↔ GLTF: full fidelity (materials, animations preserved).
  • OBJ export: geometry + basic materials, no animations.
  • STL export: geometry only — no materials, colors, or UVs.
  • Large files may take a moment; everything runs in your browser.
