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.
PLY was designed at Stanford for storing 3D-scanned data. Beyond plain geometry it can attach arbitrary per-vertex properties — most importantly vertex colors — which makes it the format of choice for 3D scans, photogrammetry output and point-cloud-derived meshes.
| AMF | PLY | |
|---|---|---|
| Geometry | Curved-triangle mesh | Triangle mesh / scan data |
| Units | Yes | No |
| Colors & materials | Colors & multi-material | Per-vertex colors |
| Animations | No | No |
| Typical use | Additive manufacturing (legacy) | 3D scans & photogrammetry |
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 PLY 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 PLY result has no declared units and does not carry textures, animation or an assembly tree.
