ENFF to COLLADA Converter
FileFlip converts ENFF to COLLADA entirely inside your browser, using Assimp compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an ENFF file to COLLADA?#
- Drop your ENFF file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to COLLADA and the conversion starts on its own. FileFlip downloads 11.2 MB of WebAssembly the first time and nothing after that, then runs Assimp on your own machine.
- Save the COLLADA file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting ENFF to COLLADA lose quality?#
Not in the sense of pixels or samples. Converting ENFF to COLLADA rebuilds the file in COLLADA's own model rather than re-encoding it, so everything COLLADA can represent comes through exactly and anything it cannot has to be dropped. Expect the geometry to be exact, and anything the target has no place for, such as a rig, to be left behind.
Is it safe to convert ENFF files online?#
Yes, because nothing is uploaded. FileFlip converts ENFF files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What ENFF to COLLADA actually does to the file#
Converting ENFF to COLLADA runs on Assimp, downloads 11.2 MB of WebAssembly the first time and nothing after that, rebuilds the file in the target's own model.
| Engine | Assimp |
|---|---|
| Conversion path | One step: ENFF → COLLADA |
| Downloaded to your browser | 11.2 MB, once, then cached by your browser |
| Quality | Rebuilt in the target's model |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Materials | Sometimes | Survives for some files and not others. |
| Textures | Sometimes | Survives for some files and not others. |
| Skeleton and animation | Sometimes | Survives for some files and not others. |
What is an ENFF file?#
An ENFF file is plain text written to the Extensions of the Neutral File Format document dated April 16, 1993, which adds positional lights with intensity and colour, an ambient shading term, and Bezier and NURBS surface patches on top of the base NFF primitives.
Use ENFF only alongside an existing renderer or scene archive that already relies on its Bezier or NURBS extensions to NFF.
Convert ENFF to OBJ or another mesh format once its patches have been tessellated into polygons a modern application can open.
What is a COLLADA file?#
A DAE file is an XML document in the COLLADA schema, created at Sony Computer Entertainment in 2004 and now maintained by the Khronos Group, describing a 3D scene's geometry, materials, lights, cameras and animation so it can move between authoring tools that don't share a native format.
Use COLLADA when a scene, not just a mesh, needs to move between two older authoring tools that both implement the schema.
Convert DAE to glTF for anything shipping to a web viewer, game engine or AR platform today, since that's the format those targets expect.
ENFF to COLLADA questions people ask#
What is an ENFF file?
An ENFF file is a Neutral File Format scene extended with positional lights, an ambient shading term, and Bezier and NURBS surface patches, on top of the spheres, cones and polygons the base NFF format supports. The extensions were documented on April 16, 1993.
How is ENFF different from NFF?
NFF describes a scene with simple primitives like spheres and flat polygons, while ENFF adds curved surfaces, Bezier and NURBS patches, along with richer positional lighting, on top of that same base syntax. An ENFF file with none of the extended features used is effectively an NFF file.
What software reads ENFF files?
Support is limited to the same small set of renderers and libraries that already handle plain NFF, with Assimp's importer being one of the few still maintained. There is no mainstream 3D application that opens ENFF directly.
What is a DAE file?
A DAE file is a COLLADA document, an XML-based interchange format created at Sony Computer Entertainment in 2004 and now maintained by the Khronos Group. It describes a full 3D scene, geometry, materials, lights, cameras and animation, so it can move between authoring tools that don't share a native format.
