Convert 3MF to OBJ online

Drop a .3mf file to turn it into OBJ. 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 OBJ

Wavefront OBJ

OBJ is a simple, widely supported text format for polygon meshes. Materials live in a separate .mtl file and textures in image files; there is no animation.

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; OBJ is already selected.

  3. 03

    Click “Convert” and the .obj file downloads.

Questions

Is the 3MF to OBJ 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. OBJ keeps them only if the format supports textures.
