About This Tool
GLB is the standard for web 3D delivery, but 3MF is the modern format for 3D printing with color and texture support. This converter exports mesh geometry, UV coordinates, and embedded texture images into a standard 3MF package compatible with 3D Builder, PrusaSlicer, and other 3MF viewers.
Tips
- 1Automatically extract model information
- 2Support mesh optimization and texture embedding
- 3Real-time 3D preview

Frequently Asked Questions
Are GLB textures preserved in the 3MF output?
Yes. Diffuse (base color) texture maps with UV coordinates are exported as embedded PNG images inside the 3MF package, using the standard 3MF texture2d and texture2dgroup resources. Normal maps, roughness, and metallic maps are not included.
Which texture types are supported?
Currently only the main diffuse/base color map (material.map) is exported. PBR auxiliary maps such as normal, roughness, and metallic are not embedded in 3MF, as the format focuses on visual color for printing and preview.
Can I use the output for multi-color 3D printing?
The exported 3MF preserves full-color textures for texture-mapped models. For filament-based multi-color printing (separate extruders per color), consider simplifying the model or using a dedicated multi-color slicer workflow.
Will animations and bones be included?
No. 3MF is a static mesh format. Animations, skeletons, and morph targets from GLB are not exported — only the default-pose mesh geometry, materials, and textures.
Which software can open the converted 3MF?
The output is compatible with Microsoft 3D Builder, PrusaSlicer, Cura, Chitubox, Fusion 360, and the Any3D 3MF viewer. Windows 10/11 also has built-in 3MF preview support.
Is conversion done locally?
Yes. All conversion runs entirely in your browser. Your GLB files are never uploaded to any server.
