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.
GLB is the single-file binary packaging of glTF, the "JPEG of 3D". One file carries geometry, materials, textures and animations, optimized for fast GPU loading. It is the standard for web 3D, AR on Android, e-commerce product viewers and real-time applications.
| AMF | GLB | |
|---|---|---|
| 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) | Web, AR & real-time delivery |
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 GLB 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 GLB result contains the converted geometry, hierarchy and flat colors, but it cannot recreate texture maps or animation that were dropped on import.
