Convert STL to AMF Online
Convert STL to AMF in seconds. STL is the standard triangulated mesh format for 3D printing; AMF's strength is this: carries color/material data beyond plain STL geometry. No software installation required — everything runs in your browser.

Why Convert STL 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 virtually every slicer and 3D-printing workflow, converting is usually the fastest path — STL and AMF serve different enough purposes that recreating the asset from scratch rarely makes sense.
This conversion comes up whenever you need 3D printing with color and material metadata, an early alternative to 3MF instead of virtually every slicer and 3D-printing workflow. STL and AMF serve genuinely different purposes, so moving between them isn't just a formality.
STL's limitation: no color, material, or multi-object metadata. AMF's strength: carries color/material data beyond plain STL geometry — it doesn't share that constraint.
How to Convert STL to AMF
- Upload your STL 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
- Understands that STL is the standard triangulated mesh format for 3D printing and AMF is an XML-based additive-manufacturing format, rather than treating the conversion as a blind format swap
- Free for files up to 50MB, 100MB for registered accounts
- Built to handle the real-world quirks of files meant for virtually every slicer and 3D-printing workflow, not just a textbook version of the format
- Produces output ready for some legacy 3D-printing tools, picking up right where every major slicer left off
- Purpose-built for the shift from virtually every slicer and 3D-printing workflow to 3D printing with color and material metadata, an early alternative to 3MF, not a generic pass-through

Frequently Asked Questions
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
What software works with the converted AMF file?
AMF is used by some legacy 3D-printing tools. If you were working with every major slicer (which produces STL), this conversion is the direct bridge between the two.
Will I lose anything converting STL to AMF?
Converting to AMF means adapting to a real constraint: far less widely adopted by current slicers than 3MF became. Anything STL carries — built as it is for virtually every slicer and 3D-printing workflow — that has no equivalent there won't make the trip, but the core content converts faithfully.
Why does AMF exist as a separate format instead of everyone just using STL?
Because they're built for different jobs — STL is aimed at virtually every slicer and 3D-printing workflow, 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.
What happens to features specific to STL that AMF doesn't have?
STL's real strength — the most universally supported format across 3D-printing software — has no equivalent once converted, since AMF's constraint is: far less widely adopted by current slicers than 3MF became.
