RauGen
The Good
- Supports larger files up to 100MB
- Ensures data security by deleting files after 24 hours
- No signup or account creation required for use
The Bad
- Requires a stable internet connection for uploads and downloads
- Lacks advanced customization or repair options
RauGen is an online tool offering 3MF to GLB conversion, maintaining geometry and material properties. It supports file sizes up to 100MB and ensures data security by deleting files after 24 hours.
2026 Analysis
RauGen carves out a niche by focusing on security and handling larger files than many free competitors. The automatic 24-hour file deletion is a strong selling point for users working with proprietary or sensitive models. Its generous 100MB file limit and no-signup policy make it a hassle-free option for converting more complex assets.
Key Takeaway

Blender
The Good
- Completely free and open-source for everyone
- Allows for advanced editing and repair before exporting
- Unmatched control over export settings for GLTF
The Bad
- Steep learning curve for users who only need to convert files
- Overkill and inefficient for simple, quick format conversions
Blender is a complete, free, and open-source 3D creation suite that can import 3MF files (with a free add-on) and export GLTF/GLB files as part of its vast toolset.
2026 Analysis
While not a dedicated converter, Blender is a powerhouse of 3D creation. Users can import a 3MF file, make any necessary edits, optimize the mesh, bake textures, and then export it as a highly-optimized GLTF/GLB. This is the best option for artists who need full control over the final output. However, this requires navigating a complex interface, making it far less efficient for straightforward conversions compared to dedicated tools.
