AMF was the ISO/ASTM attempt to fix STL for additive manufacturing: curved triangles, colors, materials and constellations in a compact XML file. Adoption ultimately went to 3MF, but AMF files still appear in research and older 3D-printing toolchains.
glTF is the Khronos royalty-free standard for transmitting 3D scenes. The JSON variant keeps the scene description human-readable with geometry in sidecar buffers, and the ecosystem — Babylon.js, Unity, Unreal, Blender and the browser engines — treats it as the native interchange format for real-time 3D.
| AMF | glTF | |
|---|---|---|
| Geometry | Curved-triangle mesh | GPU-ready triangle mesh |
| Units | Yes | Meters by spec |
| Colors & materials | Colors & multi-material | Full PBR materials |
| Animations | No | Yes |
| Typical use | Additive manufacturing (legacy) | Real-time engines & web pipelines |
Yes — free with no accounts, no watermarks and no file-size limits. Conversion runs on your own machine, so there are no server costs behind it.
No. The converter runs entirely in your browser using WebAssembly. Your .amf file never leaves your device, which makes it safe for confidential designs.
Yes — parts and assembly hierarchy are preserved where glTF supports them, and you can optionally merge everything into a single mesh during conversion.
Yes. Every converted model opens in the built-in 3D viewer with an assembly tree, display modes and section views, so you can inspect the result first.
AMF can describe richer materials than this neutral mesh pipeline keeps. Geometry, part structure and a flat part color can survive, but texture and multi-material detail cannot. The glTF result contains the converted geometry, hierarchy and flat colors, but it cannot recreate texture maps or animation that were dropped on import.
