USDZ is the file an iPhone opens in AR without an app. This converter builds one from your .glb in seconds, textures included, and it runs in this tab rather than on our servers.
Three steps, one page, no account. The whole conversion is a local operation — the slowest part is you finding the file.
Drag the file onto the box above. It is read straight off your disk with the browser's File API — no upload, and no progress bar to a server.
The file is parsed, every mesh is baked into world space, and the result is written out in the target format. Your CPU does the work, so a client's unreleased model never leaves the room.
Save the converted file and open it wherever you were headed. Nothing is watermarked and nothing expires.
They solve different problems, which is exactly why one direction of this conversion costs you something and the other does not.
GLB is the binary flavour of glTF — one file carrying geometry, UV coordinates, materials, textures and a scene graph together. It is what the web, Blender, Unity, Unreal and Three.js all read natively, and it is what this site's generator hands you.
USDZ is Apple's zipped Universal Scene Description package, and it is the file AR Quick Look wants. Send one to an iPhone and the model opens full-screen in the room, textures and all, with no app to install.
Every conversion is a trade. Any tool that tells you otherwise is lying to you, so here is the exact ledger before you commit.
USDZ is for showing, not editing. Keep the original file as the master and re-export whenever the model changes. Every other conversion here runs the same way — in your browser, free.
Convert to USDZ when the audience is on iOS and the point is to see the object in the room. It is the only export here that keeps the material, which is exactly what AR needs.
Keep the GLB as your working copy: USDZ is a delivery format, and this export writes the static scene, so anything animated arrives standing still. Open the GLB in the viewer whenever you need to check the mesh itself.
You do not have to go back to the home page. Type a prompt or drop an image, and take the .glb — free, anonymous, no watermark.
Yes. USDZ packages the images inside the file, so the model opens in AR Quick Look looking the way it did in the viewer. It is the one export on this site where the material survives the conversion intact.
No — USDZ is write-only in this converter. Keep the original GLB as your master file and re-export a USDZ whenever the model changes; that is the workflow the format was designed for anyway.
3D AI Studio generates the .glb too — free, anonymous, no watermark.
No signup, no upload, no watermark — and the converter does not care how big the file is.
