Convert OBJ to USDZ
on iPhone, privately.

OBJ needs a 3D app to open, and USDZ opens straight in AR on an iPhone. Filemorph converts the model on your iPhone, ready for AR Quick Look.

Filemorph converting an OBJ 3D model to USDZ on iPhone

OBJ is a common 3D model interchange format, but Apple's AR Quick Look, Messages and Files preview only render models in USDZ. Filemorph converts an OBJ file to USDZ locally, so the model opens in AR without a specialized 3D viewer.

Filemorph reads the OBJ file's geometry and materials with Apple's ModelIO framework and exports it directly as USDZ. Once converted, tapping the file opens Apple's AR Quick Look, letting you place the model in your surroundings through the camera, or view it as a spinnable 3D object, all without a third-party app.

How to convert OBJ to USDZ on iPhone

Pro
  1. Add your OBJ file. Open Filemorph and pick the .obj file from Files or the Share sheet.
  2. Choose USDZ. Tap Convert and choose USDZ as the output format.
  3. Save or share. Tap Convert. The USDZ saves locally — tap it to open AR Quick Look or share it directly.

In the app: Convert → OBJ → USDZ.

Why convert OBJ to USDZ?

USDZ is the format Apple's tools understand natively, so a USDZ file opens straight into AR Quick Look from Files, Messages or Mail with no app to install. Converting an OBJ model gives it that same one-tap viewing on any iPhone or iPad.

Is it private?

Yes. Unlike web converters that upload your files to a server, Filemorph converts every file locally using Apple's frameworks. Nothing leaves your device, and it works with no internet connection. This operation is part of Filemorph Pro ($29.99/year, 7-day free trial on monthly and annual plans).
