Can I convert STL to OFF in bulk for free?

Yes. Free users can batch-convert multiple files. Simply drag all your STL files into the converter at once. PRO users get higher batch limits and priority processing.

What's the difference between STL and OFF?

STL 3D Mesh is stereolithography format — the universal standard for 3d printing. OFF 3D Mesh is object file format — simple polygon mesh format. Key difference: STL 3D Mesh excels at accepted by every 3D printer and slicing software worldwide, while OFF 3D Mesh offers extremely simple format for basic 3D mesh data.

How does the STL to OFF conversion work technically?

Xonvert uses WebAssembly-compiled libraries to decode your STL file in-browser, process the 3d model data, and re-encode it as OFF. 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.

STL 3D Mesh is Stereolithography format — the universal standard for 3D printing. It is primarily used for 3D printing, rapid prototyping and CNC machining. Stores triangulated mesh data (vertices and face normals)

Will the conversion strip my EXIF or metadata?

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

Does the conversion preserve metadata?

Xonvert preserves compatible metadata fields when converting between formats. Some format-specific metadata may not carry over if the target format doesn't support it.
