CAD Export (OBJ/STL/GLB)
Drop in a STEP, IGES, BREP or mesh file, preview it, then export to OBJ, PLY, STL or GLB in one click. Free with no sign-up — everything runs locally in your browser, files are never uploaded, and batches of up to 10 files are supported.
Processing and data safety
Section titled “Processing and data safety”This tool runs entirely in your browser (local WebAssembly) — your files are never uploaded to a server.
Input and output
Section titled “Input and output”- Formats: STEP, IGES, BREP, STL, OBJ, PLY, 3MF, GLB
- Flow: STEP / IGES / BREP → OBJ / PLY / STL / GLB
How to use
Section titled “How to use”- Drop a STEP/IGES/BREP or mesh file (.stl/.obj/.ply/.3mf/.glb/.gltf) — or click Try a sample — and the parsed model previews on the page.
- Pick an output format: OBJ / PLY / STL / GLB.
- Click Convert & download — the file saves to your downloads. Nothing is uploaded; switch formats and click again to re-export the parsed model.
Key details and limits
Section titled “Key details and limits”- B-Rep files are tessellated via OCCT; precision is bounded — presets (Draft / Standard / High / Ultra) trade detail for file size.
- Output is mesh data — parametric features and assembly history are not preserved.
- Mesh inputs are converted as-is; OBJ output carries no colors or materials (no .mtl).
