Convert GLTF to ABC Online
Convert GLTF to ABC in seconds. glTF is the JSON-based "JPEG of 3D"; Alembic (ABC)'s strength is this: reliably reproduces complex simulated motion frame-by-frame. No software installation required — everything runs in your browser.

Why Convert GLTF to ABC?
glTF is the JSON-based "JPEG of 3D", commonly used for human-readable, inspectable real-time 3D scene description. That focus comes with a real limitation: splits geometry, materials, and textures across separate files. Alembic (ABC) doesn't share that problem — its strength: reliably reproduces complex simulated motion frame-by-frame.
glTF's limitation: splits geometry, materials, and textures across separate files. Alembic (ABC)'s strength: reliably reproduces complex simulated motion frame-by-frame — it doesn't share that constraint.
The short version: glTF is optimized for human-readable, inspectable real-time 3D scene description, Alembic (ABC) is optimized for transferring complex VFX simulations (cloth, fluids, crowds) between studios, and this converter exists for the moment those two needs don't line up.
How to Convert GLTF to ABC
- Upload your GLTF file.
- MiConvert converts it to ABC, aiming to preserve what makes Alembic (ABC) useful: reliably reproduces complex simulated motion frame-by-frame.
- Download the converted ABC file.
- Use it directly with Maya, Houdini, and other VFX pipelines.
Key Conversion Features
- Free for files up to 50MB, 100MB for registered accounts
- Bridges the gap between glTF's focus on human-readable, inspectable real-time 3D scene description and Alembic (ABC)'s focus on transferring complex VFX simulations (cloth, fluids, crowds) between studios
- Fast turnaround, typically under a minute per file
- No local software installation required for either side — not Three.js, Babylon.js, and most modern web 3D viewers, not Maya, Houdini, and other VFX pipelines — everything runs in the cloud
- 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

Frequently Asked Questions
Do I need Three.js, Babylon.js, and most modern web 3D viewers installed to convert my file?
No — the conversion happens entirely on our servers. You don't need Three.js, Babylon.js, and most modern web 3D viewers, and you don't need Maya, Houdini, and other VFX pipelines either unless you plan to open or edit the Alembic (ABC) result afterward.
What happens to features specific to GLTF that ABC doesn't have?
glTF's real strength — an open, widely-adopted standard for real-time 3D delivery — has no equivalent once converted, since Alembic (ABC)'s constraint is: stores baked geometry snapshots, not an editable rig or procedural setup.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
Why does ABC exist as a separate format instead of everyone just using GLTF?
Because they're built for different jobs — glTF is aimed at human-readable, inspectable real-time 3D scene description, while Alembic (ABC) is aimed at transferring complex VFX simulations (cloth, fluids, crowds) between studios. Neither format is "better," they just fit different parts of a workflow.
Is the conversion from GLTF to ABC reliable?
Straightforward files convert reliably. glTF's limitation — splits geometry, materials, and textures across separate files — combined with Alembic (ABC) expecting transferring complex VFX simulations (cloth, fluids, crowds) between studios, means unusual or edge-case source files can occasionally need a second look.
