FAQ
Common questions.
What does the converter do exactly?+
It reads a glTF 2.0 binary (.glb), cleans the geometry (welds vertices, removes duplicate data, prunes unused nodes, resamples animations), optionally downsizes textures, and produces two outputs: an AR-ready USDZ file and an optimized GLB.
Do my files leave my computer?+
No. Parsing, optimization, and USDZ export all run locally in your browser using WebAssembly. Nothing is uploaded to a server — you can even use the converter offline once the page has loaded.
Why do I need a USDZ file?+
USDZ is Apple's AR format. iOS AR Quick Look, iPhone AR previews, and Apple Vision Pro open USDZ files exclusively — a GLB link will not work on those surfaces.
How much smaller is the optimized GLB?+
It depends on the source. Models with duplicated vertices, unused nodes, or oversized textures often shrink 40–80%. The exact before/after size is shown after every conversion.
What is the free trial?+
Your first full conversion — including both downloads — is free, no account required. After that, a one-time license unlocks unlimited conversions.
How does the one-time license work?+
You buy a single license for $19 on Gumroad. Paste the license key from your receipt into the converter and it unlocks unlimited conversions on that browser. No subscription, no recurring billing.
Which inputs are supported?+
glTF 2.0 binary (.glb) files up to 150 MB. Draco-compressed inputs are not supported in the current version — re-export without Draco compression. Separate .gltf + .bin + texture folders are not supported in the browser converter.
Does it preserve animations and materials?+
PBR materials and textures are preserved. Skeletal animations are exported into USDZ when the source contains them; morph targets are not converted in the current version.
