Convert GLB to USDZ
Preparing a web asset for Apple AR Quick Look. 100% client-side — your files never leave your browser.
Drag and drop, or click to choose a GLB file. It's parsed entirely in your browser — nothing is uploaded.
USDZ is preselected on this page. Change it, adjust unit scale/axis in Options, or add more files to batch-convert.
Once conversion finishes, download the result directly, or grab the whole batch as one ZIP.
What changes when you convert GLB to USDZ
- Triangle mesh geometry
- PBR materials
- textures
- scene hierarchy / part names
- vertex or material colors
- animations
USDZ cannot represent animations — those are computed away during export, not silently corrupted.

GLB to USDZ FAQ
Is my GLB file uploaded anywhere?
No. The conversion runs 100% inside your browser using WebAssembly and client-side JavaScript. Your GLB file, and the USDZ file it becomes, never touch a server.
What does converting GLB to USDZ keep or lose?
Kept: Triangle mesh geometry, PBR materials, textures, scene hierarchy / part names, vertex or material colors. Lost: animations. USDZ cannot represent animations — those are computed away during export, not silently corrupted.
Can I convert multiple GLB files to USDZ at once?
Yes. Drop as many files as you like — they queue and convert one at a time (to keep memory use predictable), and you can download each one individually or all together as a ZIP.
Is there a file size limit?
There's no hard limit — you're bound by your device's available memory. Large batches (50+ files) convert serially to stay within a predictable memory budget.
Do I need to install any software?
No installation, plugins, or account are required. This runs in any modern browser that supports WebAssembly (Chrome, Edge, Firefox, Safari).
Will my animations still work after converting to USDZ?
USDZ has no way to store animation clips, so the converted file is a static snapshot of the model's rest pose. If you need the animation preserved, convert to GLB or glTF instead.
