Convert DAE to USDZ Online (Free & Secure)
iLove3DM converts DAE files to USDZ online and free: .dae in, .usdz out. DAE is verbose XML following the Khronos COLLADA schema, while USDZ is an uncompressed zip archive of USD scene data and textures; the converter bridges the two using GLB as an intermediate scene.

iLove3DM converts DAE files to USDZ online and free: .dae in, .usdz out. DAE is verbose XML following the Khronos COLLADA schema, while USDZ is an uncompressed zip archive of USD scene data and textures; the converter bridges the two using GLB as an intermediate scene.
Legacy and DCC formats are heavy and awkward on the web; converting them gives you a compact asset that loads in any modern browser. DAE (.dae) is verbose XML following the Khronos COLLADA schema. It holds polygon meshes with scene graph, cameras and lights and is most often opened in SketchUp, Blender, and Google Earth. USDZ (.usdz) is an uncompressed zip archive of USD scene data and textures, holding triangle and polygon meshes with Pixar USD scene structure, and is typically used in iOS AR Quick Look, Apple Vision Pro, and Reality Composer.
Because DAE uses COLLADA effects (Blinn, Phong, Lambert) with image references while USDZ uses UsdPreviewSurface PBR materials, the converter reads your scene, applies the mapping described below and writes a clean .usdz file. Everything runs in your browser or an isolated, auto-purged instance, so models stay private.
.daeAbout DAE (Collada)
ISO-standard XML schema for exchanging digital assets between graphics software applications.
- Structure: verbose XML following the Khronos COLLADA schema
- Materials: COLLADA effects (Blinn, Phong, Lambert) with image references
- Units: a unit scale declared in the asset header (often meters or inches)
- Axis: either Y-up or Z-up, as declared in the file
- Opens in: SketchUp, Blender, Google Earth, Gazebo or Rviz
.usdzTarget format: USDZ (Universal Scene Description Zip)
Apple and Pixar standard zero-compression zip archive optimized for Augmented Reality (AR Quick Look) on iOS and visionOS.
- Structure: an uncompressed zip archive of USD scene data and textures
- Materials: UsdPreviewSurface PBR materials
- Units: meters per unit, declared in the stage metadata
- Axis: Y-up
- Opens in: AR Quick Look, Reality Composer, Xcode or Blender with USD support
What happens to your data in DAE → USDZ conversion
Conversion route: DAE → GLB → USDZ (parsed into a GLB scene, then exported as USDZ).
| Aspect | Result | Outcome |
|---|---|---|
| Geometry | Preserved | DAE stores polygon meshes with scene graph, cameras and lights; USDZ stores triangle and polygon meshes with Pixar USD scene structure. Surfaces are retriangulated where needed and positions, normals and UV coordinates are carried across. |
| Materials | Preserved | DAE uses COLLADA effects (Blinn, Phong, Lambert) with image references and USDZ can represent the same information, so base colour and surface settings are preserved. |
| Textures | Preserved | In DAE, textures are referenced as external image files. USDZ can reference or embed textures too, so images and UV mapping stay linked. |
| Vertex colours | Preserved | Per-vertex colours in DAE are written to USDZ as vertex colour data. |
| Animation | Adapted | DAE provides skeletal animation, controllers and kinematics. USDZ supports only basic skeletal and transform animation, so complex rigs may be simplified. |
| Units & scale | Adapted | DAE uses a unit scale declared in the asset header (often meters or inches); USDZ uses meters per unit, declared in the stage metadata. Check the scale in your target application, and use the Scale tool if the model looks too big or too small. |
| Orientation | Adapted | DAE is either Y-up or Z-up, as declared in the file and USDZ is Y-up. The converter writes a consistent orientation, but verify the up axis in your target software. |
Expect the USDZ file to be roughly 2.3x smaller than the DAE source, since USDZ is medium, because the zip is stored without compression.
Why convert DAE to USDZ?
Why leave DAE
People most often convert from DAE when they are retiring an XML-heavy archive into a compact format. Other common cases include opening a SketchUp or robotics export in a modern pipeline and making a legacy Collada asset viewable on the web. In DAE → USDZ specifically, preserved: geometry, materials, textures, and vertex colours; adapted: animation, units & scale, and orientation. Expect the USDZ file to be roughly 2.3x smaller than the DAE source, since USDZ is medium, because the zip is stored without compression.
Why choose USDZ
USDZ is the right target when you are delivering assets to Apple developers. It also fits scenarios such as launching one-tap AR on iPhone, iPad and Apple Vision Pro and publishing Shopify or e-commerce AR previews. Legacy and DCC formats are heavy and awkward on the web; converting them gives you a compact asset that loads in any modern browser.
Where the result opens
After conversion you can open the .usdz file in AR Quick Look, Reality Composer, Xcode or Blender with USD support.
Step-by-Step Guide: DAE → USDZ
- 1
Upload your .dae file
Drag your DAE model onto the converter or click to browse. Textures are referenced as external image files; zip the model with its textures and companion files if you want them included.
- 2
Check your free quota
Free accounts can run a few conversions per day; signing in unlocks tracking of your remaining uses. No watermark is ever added.
- 3
Convert to USDZ
Press the Convert to USDZ button. The pipeline follows DAE → GLB → USDZ (parsed into a GLB scene, then exported as USDZ), which usually takes a few seconds for models under 100 MB.
- 4
Download the .usdz file
Your USDZ file downloads automatically. Open it in iOS AR Quick Look and Apple Vision Pro to confirm scale and orientation.
Tips for DAE → USDZ
- Z_UP files appear lying on their side in Y-up tools (DAE source).
- Outside the Apple ecosystem few editors can open it (USDZ target).
- Always verify real-world size: DAE is a unit scale declared in the asset header (often meters or inches), while USDZ is meters per unit, declared in the stage metadata.
- Since DAE is much heavier than USDZ, converting is also a good way to shrink your asset.
Frequently Asked Questions
How do I convert DAE to USDZ without losing quality?
Upload the .dae file and press convert; the route is DAE → GLB → USDZ (parsed into a GLB scene, then exported as USDZ). Geometry is carried over exactly; materials are preserved, and textures stay linked through UV coordinates.
Does DAE to USDZ conversion keep textures?
In DAE, textures are referenced as external image files. USDZ can reference or embed textures too, so images and UV mapping stay linked.
Why does my USDZ model look the wrong size or rotation?
DAE uses a unit scale declared in the asset header (often meters or inches); USDZ uses meters per unit, declared in the stage metadata. Check the scale in your target application, and use the Scale tool if the model looks too big or too small. DAE is either Y-up or Z-up, as declared in the file and USDZ is Y-up. The converter writes a consistent orientation, but verify the up axis in your target software.
Will the USDZ file be bigger or smaller than my DAE file?
Expect the USDZ file to be roughly 2.3x smaller than the DAE source, since USDZ is medium, because the zip is stored without compression.
What software can open the converted USDZ file?
USDZ files open in AR Quick Look, Reality Composer, Xcode or Blender with USD support. If you need to go back, use the USDZ to DAE converter.
Is it safe to upload my DAE model?
Yes. Files are processed in your browser or on isolated instances and purged right after conversion. They are never used to train AI models, and no watermark is added.
