Add your AMF file
Drop one or more .amf files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
AMF to GLTF
Converting a .amf mesh to .gltf rewrites the same triangles for a different toolchain. Free, private, and validated — the file never leaves your browser.

Converting a .amf mesh to .gltf rewrites the same triangles for a different toolchain. An .amf file is an XML manufacturing model designed as a richer successor to STL. It represents vertices and triangular volumes and can also describe units, colours, materials and curved triangles.
A .gltf file is the JSON form of Khronos glTF 2.0: it describes nodes, meshes, accessors, and buffer references in text, often pairing with external .bin buffers or embedding them as data: URIs. It is the editable, inspectable sibling of binary .glb. For this route the practical draw is human-readable scene description and same data model as GLB, so round-trips are straightforward — balanced against external buffer URIs make a lone .gltf file incomplete, which is worth knowing before you commit a large batch.
Why convert AMF to GLTF?
The practical trigger for this conversion is usually a mismatch: with .amf, far less widely supported than STL or 3MF. Switching to .gltf buys you human-readable scene description, which is why it is the better fit for inspecting or hand-editing mesh package structure. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
AMF vs GLTF at a glance
| Aspect | Additive Manufacturing Format (.amf) | glTF mesh (.gltf) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Vector — resolution-independent geometry instead of pixels |
| How it stores data | the root amf element may declare a unit such as millimetre, inch or metre | uTF-8 JSON with required asset.version 2.0 and optional scenes, nodes, meshes, accessors, bufferViews, and buffers |
| Strongest at | recovering printable geometry from an AMF archive | inspecting or hand-editing mesh package structure |
| Weak spot | far less widely supported than STL or 3MF | external buffer URIs make a lone .gltf file incomplete |
| Metadata | geometry is preserved; unit, colour, material and object metadata may be flattened or omitted according to the selected target | copyright and generator strings sit under asset; application-specific data is commonly stored in extras |
Pick GLTF as the output
Select .gltf in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if GLTF is selectable, the route is real and validated.
Convert on your device
Press Convert. The mesh is parsed, retriangulated where needed, and rewritten locally with full validation.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid GLTF file. Outputs keep the original filename with the .gltf extension.
AMF to GLTF questions, answered
Will converting AMF to GLTF lose quality?
Since amf is lossless-oriented and gltf is vector-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .gltf itself requires.
Is it private to convert AMF files here?
Yes — the .amf file is processed inside your browser tab and never uploaded. The mesh is parsed, retriangulated where needed, and rewritten locally with full validation. Close the tab and the file is gone from memory.
Where will the GLTF file work?
The same ecosystem that reads .glb generally reads .gltf, provided referenced buffers resolve. Browser viewers, Blender, and engine importers expect either embedded data URIs or co-located .bin files.
Will the GLTF file be bigger or smaller than my AMF?
It depends on the content: uTF-8 JSON with required asset.version 2.0 and optional scenes, nodes, meshes, accessors, bufferViews, and buffers. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my AMF file?
In .amf, geometry is preserved; unit, colour, material and object metadata may be flattened or omitted according to the selected target. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
