Convert USDZ to glTF
Convert USDZ to glTF in your browser. The conversion runs on this page and the file never leaves your computer.
Result
Before you convert: what this keeps and what it destroys
Preserved
- The geometry, triangle for triangle
- Overall dimensions and proportions
- Watertightness, where the input is watertight
- Colour
- Separate parts and their positions
Destroyed
- A recorded unit: glTF stores none

Why people convert USDZ to glTF
Moving from Apple's AR format to the open standard, in the readable container. Take the GLB instead if you just want the file to work; take this one when you want to see the node tree and the materials as JSON.
The buffer is embedded as base64 so the result is still a single file, at about a third more size than the binary equivalent.
Both formats are metre-based, so nothing is rescaled. The conversion is possible only where the USDZ holds a text USDA stage, which is the same constraint every route out of this format has here, and the reason is simply that the binary USDC crate format has no browser-side reader.
What you get
You get a plain-text glTF file you can open in an editor containing the same triangles the USDZ file described. No geometry is added, removed or approximated: mesh-to-mesh conversion is a change of container, and this site's tests check that the triangle count comes out identical.
The output uses metres, as required by the glTF specification.
Carried across: supported base or vertex colour, the supported part structure.
The conversion runs in your browser. Your file stays on your computer and is not uploaded.
What to check afterwards
- USDZ declares its unit in the file. Check the output dimensions in the receiving application, especially when its import settings can override the unit.
If you need something this conversion cannot give you
This pair loses very little. glTF carries what USDZ carries, so the main reason to choose a different target is what the receiving software accepts.
Going the other way
Convert glTF back to USDZ. The reverse conversion also works with mesh geometry. It does not reconstruct exact CAD surfaces. Material data and part structure lost in either direction cannot be restored by converting back. Keep the original file for later edits.
How we know this conversion works
This pair was checked against 4 files from the test corpus on 2026-09-04. Each run parses its own output back in and compares the bounding box, the triangle count and, for closed solids, the volume against the input.
A pair that fails those checks doesn't get a page. That's why this site lists 120 conversions and not the several hundred a format-times-format grid would suggest.
