Frequently Asked Questions

What 3D formats can I convert from?

You can import GLB, GLTF, OBJ, STL, FBX, PLY, and DAE (Collada) files.

What 3D formats can I convert to?

You can export to GLB, OBJ, STL, USDZ, and PLY formats.

Are textures preserved during conversion?

Textures are preserved when converting to GLB or USDZ. OBJ, STL, and PLY exports contain geometry only.

Is there a file size limit?

There is no hard file size limit. However, very large files (over 100 MB) may cause slowdowns depending on your device memory.
