How to convert AMF to GLB
- 1Add your AMF fileDrop the .amf file into the box, or pick it from disk. Multiple files are converted one after another.
- 2Pick GLB as the outputGLB is already selected on this page. Adjust scale, up axis or triangle budget if the target application is picky.
- 3Download the resultThe .glb file is written locally and appears as a download button next to your file.
About AMF
AMF was the ASTM standard intended to replace STL, adding units, curved triangles, colours, materials and lattices. 3MF ended up winning industry adoption, but AMF files still appear in research and older printer software.

About GLB
GLB packs an entire glTF 2.0 scene, including textures and animation clips, into one binary file. It is the format of choice for the web, AR and real time engines because it loads fast and needs no external assets.

Questions
Is this AMF to GLB converter free?
Yes. There is no account, no daily quota and no watermark. The tool is a static web page and the work is done by your own CPU, so there are no server costs to pass on.
Are my files uploaded anywhere?
No. MeshFormat loads a WebAssembly build of the geometry kernels into your browser and reads the file locally. You can open the network tab and confirm that nothing leaves the page, or disconnect after the page has loaded and keep converting.
How large can a AMF file be?
The practical limit is your available memory rather than an arbitrary cap. Models up to a few hundred megabytes work on a normal laptop; very dense scans convert faster if you lower the triangle budget in the options.
Which programs open GLB files?
three.js, Babylon.js, Unity, Unreal Engine and most other tools that work with 3D meshes read .glb directly.
