Free online 3D file converter
Turn a GLB or glTF model into STL (for 3D printing), OBJ, PLY or GLB — right here, in seconds. No sign-up, no watermark.

Private by design
Conversion runs on-device with WebGL — nothing is uploaded, so even confidential models are safe.
Print-ready STL
Export straight to STL and drop it into OrcaSlicer, Bambu Studio, Cura, PrusaSlicer or Creality Print.
OBJ, PLY & GLB
Hand off to DCC tools and engines, or re-pack a tidy single-file GLB.
Need more formats?
Grafy also exports USDZ (AR), 3MF (multi-color print), FBX and STEP from your models.
Make the model, then convert it
Grafy turns a photo, a few images, or a text prompt into a textured 3D model you can rig, animate, remesh, print-prep and export — all on one visual canvas.
