Your models stay local.

Files and filenames are not uploaded for processing. Parsing and conversion run in browser workers, and downloads are generated on your device. CAD and FBX runtime assets load from this site when needed. No account or persistent file storage is used.

From file to download

Choose a file. The workbench checks its format and resource limits.
Inspect the preview, units and warnings, then choose an available output.
Run the conversion and download the result. Reset or replace the file to start another job.

Choose what your next file should preserve

STL carries triangles, STEP carries CAD surfaces, and scene or manufacturing packages can hold more than geometry. A conversion may preserve the shape while discarding other information.

Compare geometry, units and format tradeoffs
