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.
USDZ packages Pixar’s Universal Scene Description into a single uncompressed ZIP for Apple’s AR Quick Look. An iPhone or iPad can open a USDZ link directly into augmented reality from Safari — no app required — which makes it the format for AR product previews on Apple devices.
| AMF | USDZ | |
|---|---|---|
| Geometry | Curved-triangle mesh | USD mesh scenes |
| Units | Yes | Meters (implied) |
| Colors & materials | Colors & multi-material | PBR materials |
| Animations | No | Yes |
| Typical use | Additive manufacturing (legacy) | Apple AR Quick Look |
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 USDZ 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 USDZ result contains the converted geometry and flat colors, but no source textures, rigs or animation tracks.
