What Is a USD / USDZ File?
Universal Scene Description was written at Pixar to assemble whole films out of layers that hundreds of artists edit at once, and released as open source in 2016. It is now governed by the Alliance for OpenUSD (Apple, NVIDIA, Adobe, Autodesk and Pixar) and is the scene format behind NVIDIA Omniverse.
It comes in three encodings, and this viewer opens all of them: .usda is a readable text layer, .usdc is the binary “crate” the same data compiles to, and .usdz is an uncompressed zip that bundles a layer with its textures so one file carries the whole asset. .usd is either encoding, told apart by its bytes. USDZ is what Apple made the format famous with: it is the file every iPhone writes for AR Quick Look, Object Capture and RoomPlan.
Who Uses USD / USDZ Files?
iPhone and iPad owners sharing an AR model, a room scan or an Object Capture photogrammetry scan; retailers publishing AR-ready product models; film and animation studios working in Houdini, Maya, Katana and RenderMan; and anyone building scenes in NVIDIA Omniverse, Blender, Cinema 4D or Unreal.
Common Use Cases
- Open a .usdz someone shared from an iPhone, on any device
- Check an Object Capture or RoomPlan scan before using it
- Review an AR Quick Look product model on a desktop browser
- Convert USDZ to GLB for the web, or to OBJ / STL for CAD and printing
- Measure a scan at real-world scale, in the units the stage declares
Features
Open Instantly
Drag and drop a .usdz, .usdc, .usda or .usd — the stage is composed in your browser, nothing is uploaded.
iPhone Scans
Object Capture, RoomPlan and AR Quick Look files open as they were shared, on any device.
Textures Included
The images bundled inside a .usdz are unpacked and applied, so the model arrives the way it left.
Real-World Scale
Size comes from the stage’s own metersPerUnit, so a scan measures in its real units.
All Three Encodings
The binary .usdc crate, the ASCII .usda layer and the .usdz package are read alike.
Convert to GLB
Export as glTF Binary — the equivalent single-file package for the web.
Convert to OBJ or STL
Save as OBJ for Blender and Maya, or STL to 3D print a scan.
Export as PDF
Generate a snapshot PDF for a review or a report.
No Upload Required
Your file is parsed entirely in your browser. Nothing leaves your device.
Embed on Any Site
Add the USDZ viewer to your website with a single iframe embed code.
Compatibility & Format Notes
Meshes, the prim hierarchy, UsdPreviewSurface materials and the textures bundled inside a .usdz all load, as do USD’s geometric primitives (sphere, cube, cylinder, cone, capsule, plane). Scale comes from the stage’s own metersPerUnit, so an iPhone scan measures in centimetres without being told. A loose .usda or .usdc that references other layers needs those files too — the viewer names the ones it is missing. Animation and skeletal playback are not exposed in the toolbar.

Frequently Asked Questions
▶What is the difference between USD and USDZ?
USDZ is a package: an uncompressed zip holding one USD layer plus every texture it uses, so a single file carries the whole asset. USD (.usd, .usda, .usdc) is the layer on its own, which often references other files sitting next to it. If you are sending a model to someone, send the .usdz.
▶Can I open an iPhone .usdz on Windows or Android?
Yes — that is what this page is for. AR Quick Look is iOS-only, so a .usdz shared from an iPhone has nowhere to open on a Windows PC or an Android phone. Drop it here and it renders in the browser, textures and all, with nothing uploaded.
▶Why does my .usda open empty?
Almost always because it is one layer of a set. A published USD asset is split across files — geometry in one, materials in another, a small root layer stitching them together — and uploading the root alone brings no geometry with it. The viewer names the files it was looking for. Export the asset as a .usdz, or upload the whole folder as a .zip, and everything resolves.
▶Can I convert USDZ to GLB?
Yes — click Export → glTF Binary. GLB is the equivalent single-file package for the web, and the two formats carry much the same thing: meshes, PBR materials and embedded textures. OBJ, STL, PLY and a PDF snapshot are in the same menu.
▶Is this USD viewer really free?
Yes, completely free. No signup, no watermarks, no file size limits on the viewer (the optional share-link feature has a 100 MB upload cap). Built by Innerscene as a tool for architects, engineers, and designers.
▶Are my files uploaded to a server?
No. All parsing, rendering, and conversion runs in your browser — nothing is uploaded, stored, or transmitted by default. The Share button is the only feature that uploads a file, and only when you explicitly click it.
▶Can I convert to another format?
Yes. Click Export in the toolbar to save as STL (3D printing), OBJ (Wavefront), GLB (glTF binary), or PDF (snapshot of the current view).
▶Can I embed this viewer on my own site?
Yes. Click Embed in the toolbar to generate a one-line <iframe> snippet you can paste into any HTML page. You can choose whether the embed shows the viewer’s toolbar.
