Convert 3MF to glTF online

Drop a .3mf file to turn it into glTF. You see the model in 3D before converting, and the file never leaves your device.

About 3MF

3D Manufacturing Format

3MF is the modern 3D printing format: units, colors, multiple objects and print settings in one zip archive.

About glTF

GL Transmission Format 2.0

glTF is the JSON flavour of glTF 2.0. The scene description lives in the .gltf file, while geometry sits in a .bin file and textures in images — select them all together.

How it works

  1. 01

    Drop the .3mf file (with its textures or .bin/.mtl files, if any).

  2. 02

    Check the model in the 3D preview; glTF is already selected.

  3. 03

    Click “Convert” and the .gltf file downloads.

Questions

Is the 3MF to glTF converter free?+

Yes, without limits, sign-up or watermark.

Is my 3MF file uploaded?+

No. The 3MF file is read and converted in your browser; nothing is sent to a server.

Why are textures missing after converting 3MF?+

Textures stored as separate files must be selected together with the model. glTF keeps them only if the format supports textures.
