Convert STL to USDZ
Convert a STL file to USDZ in your browser. Free, no upload, no sign-up.
Convert STL files to USDZ directly in your browser. The converter parses the STL mesh, rebuilds it in memory and writes it out as USDZ, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. USDZ lets iPhone and iPad users view the model in augmented reality directly from Safari, with no app required.
How to convert STL to USDZ
- 1Drop your STL file
Drag a .stl file onto the box above or click to choose one.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the USDZ
Adjust the export options if needed and click download. Geometry and basic materials are exported. Meshes without materials get a neutral gray so AR Quick Look renders them.
What is a STL file?
STL is the oldest and most widely supported 3D printing format. It stores nothing but a list of triangles, with no color, texture, unit or scale information. Every slicer and almost every 3D tool can read it, which is why it is still the default exchange format for printable models.
Commonly used by: 3D printer slicers (Cura, PrusaSlicer, Bambu Studio), CAD export, Thingiverse / Printables
What is a USDZ file?
USDZ is Apple's packaging of Pixar's Universal Scene Description. It is the format iOS uses for AR Quick Look: open a .usdz link in Safari and the model appears in your room through the camera. It stores meshes, PBR materials and textures in a single uncompressed ZIP.
Commonly used by: Apple AR Quick Look, iPhone and iPad, Reality Composer, Pixar USD pipelines
USDZ lets iPhone and iPad users view the model in augmented reality directly from Safari, with no app required.
