Convert GLTF to AMF Online
Convert GLTF to AMF in seconds. glTF is the JSON-based "JPEG of 3D"; AMF's strength is this: carries color/material data beyond plain STL geometry. No software installation required: you upload the file here and the conversion runs on our servers.

Why Convert GLTF to AMF?
AMF is an XML-based additive-manufacturing format, built around 3D printing with color and material metadata, an early alternative to 3MF. Converting from glTF — built around human-readable, inspectable real-time 3D scene description instead — closes that gap.
glTF is typically produced by or used with Three.js, Babylon.js, and most modern web 3D viewers, for human-readable, inspectable real-time 3D scene description. AMF is expected by some legacy 3D-printing tools instead, for 3D printing with color and material metadata, an early alternative to 3MF — converting bridges that gap.
glTF's limitation: splits geometry, materials, and textures across separate files. AMF's strength: carries color/material data beyond plain STL geometry — it doesn't share that constraint.
How to Convert GLTF to AMF
- Upload your GLTF file.
- MiConvert converts it to AMF, aiming to preserve what makes AMF useful: carries color/material data beyond plain STL geometry.
- Download the converted AMF file.
- Use it directly with some legacy 3D-printing tools.
Key Conversion Features
- Built to handle the real-world quirks of files meant for human-readable, inspectable real-time 3D scene description, not just a textbook version of the format
- Purpose-built for the shift from human-readable, inspectable real-time 3D scene description to 3D printing with color and material metadata, an early alternative to 3MF, not a generic pass-through
- Fast turnaround, typically under a minute per file
- Produces output ready for some legacy 3D-printing tools, picking up right where Three.js, Babylon.js, and most modern web 3D viewers left off
- Keeps the parts of your file that matter for 3D printing with color and material metadata, an early alternative to 3MF intact, even though the source was built for human-readable, inspectable real-time 3D scene description

Frequently Asked Questions
What happens to features specific to GLTF that AMF doesn't have?
glTF's real strength — an open, widely-adopted standard for real-time 3D delivery — has no equivalent once converted, since AMF's constraint is: far less widely adopted by current slicers than 3MF became.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Is the conversion from GLTF to AMF reliable?
Straightforward files convert reliably. glTF's limitation — splits geometry, materials, and textures across separate files — combined with AMF expecting 3D printing with color and material metadata, an early alternative to 3MF, means unusual or edge-case source files can occasionally need a second look.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
What software works with the converted AMF file?
AMF is used by some legacy 3D-printing tools. If you were working with Three.js, Babylon.js, and most modern web 3D viewers (which produces glTF), this conversion is the direct bridge between the two.
