One converter, five 3D formats

Convert FBX to OBJ

Open a FBX model, inspect the parsed geometry and export a OBJ copy. The page explains format-specific losses before download.

  • 20 conversion directions
  • STL · GLB · OBJ · FBX · 3MF
  • Static geometry preview

FBX to OBJ converter

Files up to 200 MiB; scenes are bounded to 100 meshes and 4,200,000 triangles.

OBJ output writes static geometry and preserves normals and UV coordinates when they exist; MTL and texture files are not packaged.

Waiting for a file.

All supported conversions

Choose any source and a different target. Every link opens the same converter with that pair selected.

How the 3D converter works

1

Choose both formats

Set the real source format and the format you need to download.

2

Open and inspect

The browser parses the model and shows dimensions, mesh count and format-loss warnings.

3

Download the conversion

Export the visible static geometry and verify scale and materials in the destination application.

What changes from FBX to OBJ

A FBX source can contain triangle geometry, normals, UV coordinates, materials and colors, textures, object hierarchy or component relationships, rigs and animation.

OBJ is a unitless static mesh format. This download contains one OBJ file and does not bundle MTL or texture sidecars.

Scale path: The converter reads FBX unit metadata when possible; the source-unit selector can override it. OBJ output is unitless and keeps coordinates in the millimeter working scale.

Guaranteed in this conversion: triangle geometry.

When present, the exporter may retain normals, UV coordinates; verify them in the downloaded file.

This static conversion does not transfer materials and colors, textures, object hierarchy or component relationships, rigs and animation.

Limits and checks you still need

  • The first release exports the visible static mesh; rigs, animation clips, cameras and lights are not guaranteed across formats.
  • OBJ is handled as one geometry file, without separate MTL files or external textures.
  • Large or unusually complex files can exceed browser memory even below the file-size limit.

Frequently asked questions

Can I convert FBX to OBJ for free?

Yes. The converter runs without an upload API or account and downloads the result from this tab.

Does the model leave my device?

No model bytes are sent to AIPRINTGEN. Libraries load only when needed, then conversion uses the local File object.

Will textures and animation survive?

Not in every direction. The warning beside the result reflects the selected target; inspect the downloaded file in its destination app.

Why should I check the scale?

STL and OBJ do not declare a universal unit, while GLB, FBX and 3MF have different unit conventions.

«Lately we've been using this service more often than the foreign ones»

«I did nothing to the model at all. As soon as it generated, I sent it straight to print. I used a text prompt. I think it turned out really great»

«I've tried every generator except Sloyd, and I can say aiprintgen is the best. I took 4 photos and ran them through almost every generator available. All of them except printgen produced a model with artefacts I'd have had to fix in Blender. This one got it right straight away. I only had 2 angles, so instead of the side views I didn't have I uploaded what I did — and it still managed an almost perfect model from two views. The other generators produced complete rubbish from two views. In short, aiprintgen makes excellent models for 3D printing, the interface isn't cluttered, it's simple and clear, and I already recommend it to everyone I know. Not the most important thing, but a nice bonus: the menu is in Russian»

«As a wood sculptor, the program helps a lot in this area: even when we ask for a rough, dynamic sculpture, we get a picture and a 3D model as an example»

«Blok, Pasternak, Mayakovsky and Bulgakov with Mandelstam all came out well for me. Some from 1 photo, some from 4. I'm not too demanding, and it's fine for me»
