GrafyFree 3D file converter

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.

Everything runs in your browser — your file is never uploaded.

Drop a GLB / glTF file

or click to choose one from your device

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.

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.
