What's the difference between STEP and FCSTD?

STEP 3D Model is iso standard for 3d cad data exchange across all engineering software. FreeCAD Project is freecad native project file — open-source parametric 3d cad. Key difference: STEP 3D Model excels at universal CAD interoperability, mathematically precise geometry, while FreeCAD Project offers full parametric CAD data in a free, open-source application.

How does the STEP to FCSTD conversion work technically?

Xonvert uses WebAssembly-compiled libraries to decode your STEP file in-browser, process the cad data, and re-encode it as FCSTD. All processing happens on your device's CPU.

What happens to my files after conversion?

Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.

STEP 3D Model is ISO standard for 3D CAD data exchange across all engineering software. It is primarily used for engineering product data exchange and cross-CAD collaboration. ISO 10303 (STandard for Exchange of Product model data)

Will the conversion strip my EXIF or metadata?

Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target FCSTD format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
