Convert GLB to AMF Online
Convert GLB to AMF in seconds. GLB is the compact binary form of glTF; AMF's strength is this: carries color/material data beyond plain STL geometry. No software installation required — everything runs in your browser.

Why Convert GLB to AMF?
If you need a file built for 3D printing with color and material metadata, an early alternative to 3MF but only have one built for fast-loading real-time delivery for web and AR viewers, converting is usually the fastest path — GLB and AMF serve different enough purposes that recreating the asset from scratch rarely makes sense.
GLB's limitation: not natively supported by many older DCC and game-engine importers. AMF's strength: carries color/material data beyond plain STL geometry — it doesn't share that constraint.
GLB is the compact binary form of glTF, commonly used for fast-loading real-time delivery for web and AR viewers. That focus comes with a real limitation: not natively supported by many older DCC and game-engine importers. AMF doesn't share that problem — its strength: carries color/material data beyond plain STL geometry.
How to Convert GLB to AMF
- Upload your GLB 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 fast-loading real-time delivery for web and AR viewers, not just a textbook version of the format
- Free for files up to 50MB, 100MB for registered accounts
- Purpose-built for the shift from fast-loading real-time delivery for web and AR viewers to 3D printing with color and material metadata, an early alternative to 3MF, not a generic pass-through
- No local software installation required for either side — not Three.js, Babylon.js, iOS/Android AR viewers, not some legacy 3D-printing tools — everything runs in the cloud
- Understands that GLB is the compact binary form of glTF and AMF is an XML-based additive-manufacturing format, rather than treating the conversion as a blind format swap

Frequently Asked Questions
Why does AMF exist as a separate format instead of everyone just using GLB?
Because they're built for different jobs — GLB is aimed at fast-loading real-time delivery for web and AR viewers, while AMF is aimed at 3D printing with color and material metadata, an early alternative to 3MF. Neither format is "better," they just fit different parts of a workflow.
Is AMF objectively better than GLB?
Not objectively — AMF is better specifically for 3D printing with color and material metadata, an early alternative to 3MF. For fast-loading real-time delivery for web and AR viewers, GLB is still the right tool; that's exactly why both formats exist.
What's the real difference between GLB and AMF?
GLB is built around fast-loading real-time delivery for web and AR viewers (the compact binary form of glTF). AMF is built around 3D printing with color and material metadata, an early alternative to 3MF instead (an XML-based additive-manufacturing format) — different enough that this is a genuine format conversion, not just a rename.
What happens to features specific to GLB that AMF doesn't have?
GLB's real strength — a single efficient file bundling geometry, materials, and textures — has no equivalent once converted, since AMF's constraint is: far less widely adopted by current slicers than 3MF became.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
