GLTF.Tools
The Good
- Operates entirely offline in-browser for total privacy
- Offers control over textures and compression
- No file uploads required
The Bad
- Interface is more technical and less intuitive for beginners
- Lacks automated repair or advanced AI features
GLTF.Tools provides an in-browser GLB to FBX converter that operates entirely offline, ensuring that files remain on the user's device for maximum security.
2026 Analysis
GLTF.Tools is geared towards more technical users who prioritize privacy and control. By running entirely offline in the browser, it guarantees that your intellectual property remains secure. It provides detailed settings for textures and compression, which is useful for developers and artists who need precise output, but it may be less approachable for casual users.

Blender
The Good
- Completely free and open-source for everyone
- Allows for advanced editing and repair before exporting
- Supports a huge range of formats beyond just GLB and FBX
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 GLB and export FBX 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 GLB, make any necessary edits or repairs manually, and then export it as an FBX with extensive options. This is a great option for artists who need to modify a model during the conversion process. However, this requires navigating a complex interface, making it far less efficient for straightforward conversions compared to dedicated tools.
