Free 3D converter

Convert 3MF to GLB

Drop a 3MF file and download it as GLB. The conversion runs in your browser, so the file never leaves your device. It keeps the exact shape and materials and textures.

Free, no sign-up, and your file stays on your device.

Converted to GLB in your browser. Nothing is uploaded.

GLB, glTF, OBJ, STL, PLY, FBX or 3MF, up to 300 MB. Add .mtl, .bin and texture files alongside.

What carries over from 3MF to GLB

Checked against what the converter writes, not just what the formats allow.
Shape (triangles)
Kept exactly
UV coordinates
Kept
Colour texture
Kept
PBR maps (roughness, metalness, normal)
Not in 3MF
Vertex colours

Animation
Not in 3MF
Separate parts

Size and units
Millimetres become metres, so the model opens at its real size.
Up direction
Turned Y up, so the model stands upright in viewers.

How to convert 3MF to GLB

  1. Add your 3MF

    Drop the .3mf file or choose it from your device.

  2. Check the preview

    Turn the model and check what will be kept before converting.

  3. Download the GLB

    The .glb is written in a second or two for most models.

When to convert 3MF to GLB

  • To put it on the web

    GLB is what three.js, Google's <model-viewer> and most web viewers load: one file, textures included.

  • For Blender and Godot

    Both import glTF natively, with materials, so there is no .mtl or texture folder to keep together.

The two formats

3MF

3D Manufacturing Format

3MF is an open, zip-based XML format from the 3MF Consortium (founded in 2015) built to replace STL for printing. Unlike STL it records units, so a model always opens at the right size.

Usually comes from
Bambu Studio and PrusaSlicer projects, MakerWorld and Printables downloads
Opens in
every major slicer: Bambu Studio, PrusaSlicer, OrcaSlicer, UltiMaker Cura and Lychee
Units
Recorded in the file (millimetres when written here)
Up axis
Z up

GLB

Binary glTF 2.0

GLB is the single-file, binary form of glTF 2.0, the open format the Khronos Group published in 2017 for delivering 3D assets. Mesh, materials, textures and animation all travel in one file.

Usually comes from
AI 3D generators (including PhotoGenius), Sketchfab downloads, web 3D projects and game asset stores
Opens in
Blender, Godot, three.js and most web viewers, Android's Scene Viewer, Bambu Studio and UltiMaker Cura, Unreal's glTF importer, and Unity with the glTFast package
Units
Metres

Y up

Questions

Something else? Ask us and a person will answer.

Is this 3MF to GLB converter free?

Yes. There is no account, watermark or limit on conversions. It accepts files up to 300 MB; how large a model your browser can handle depends on your device's memory.

Is my file uploaded?

No. The conversion runs in your browser with the open-source three.js loaders and exporters, so your 3MF never leaves your device.

Does the GLB keep textures and animation?

Yes, everything the 3MF has that glTF supports: geometry, UVs, materials and textures embedded in the file.

Can I make a 3D model from a photo instead?

Yes. PhotoGenius turns a photo or a text prompt into a textured GLB with Rodin Gen-2.5, Rodin Gen-2.5 Fast, Tripo H3.1, TRELLIS.2, Rodin Gen-2 or Hunyuan3D 3.1, which you can then convert here. See Image to 3D model.

Turn a photo into a 3D model

Rodin Gen-2.5, Rodin Gen-2.5 Fast, Tripo H3.1, TRELLIS.2, Rodin Gen-2 or Hunyuan3D 3.1 builds a textured GLB from one image. The price shows before you run it.
