Convert AMF to GLB
Convert a AMF file to GLB in your browser. Free, no upload, no sign-up.
Convert AMF files to GLB directly in your browser. The converter parses the AMF mesh, rebuilds it in memory and writes it out as GLB, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. GLB is the format web browsers, AR viewers and e-commerce platforms expect; one self-contained file with materials included.
How to convert AMF to GLB
- 1Drop your AMF file
Drag a .amf file onto the box above or click to choose one. Plain and ZIP-compressed AMF files are read; curved-triangle data is flattened.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the GLB
Adjust the export options if needed and click download. Meshes without materials get a neutral gray PBR material so the file renders correctly in viewers.
What is a AMF file?
AMF is an XML format standardised as ISO/ASTM 52915 as an intended successor to STL. It supports units, colors, materials and curved triangles. Adoption stayed limited and most of the industry moved on to 3MF, but slicers still accept AMF files.
Commonly used by: older slicers, ASTM / ISO 52915 workflows

What is a GLB file?
GLB is the binary container for glTF 2.0, the "JPEG of 3D" maintained by the Khronos Group. A single .glb file bundles geometry, PBR materials, textures and animations, and is the standard format for 3D on the web and in AR viewers.
Commonly used by: web viewers (three.js, model-viewer), AR on iOS and Android, Sketchfab, game engines
