OBJ to USDZ converter
Drop an OBJ file and get a USDZ back in seconds. OBJ is plain text, read almost everywhere, used mostly for older 3D software and CAD-adjacent tools. USDZ is Apple's AR package, the usual choice for iPhone and iPad AR Quick Look and Apple Vision Pro. The conversion runs entirely in your browser, so your file never leaves your device.

Questions
- Is my OBJ file uploaded?
- No. The OBJ is parsed and the USDZ is written by JavaScript in your browser tab. The file never reaches our servers.
- Will the USDZ look the same as the OBJ?
- The geometry is identical. USDZ keeps materials and textures too. See the notes above for this exact pair.
- Is there a file size limit?
- Files up to 150 MB open, but very large models depend on your device's memory. Desktop browsers handle big files best.
