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.

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.
In the app: Convert → OBJ → 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.
