Frequently asked questions
Are my files uploaded?
No. Model parsing, preview, and export run in your browser.

No format conversion is described as lossless. Review the format-specific warnings above before using the output.
What is the file-size limit?
100 MB is a safety ceiling, not a guarantee. Mobile devices may need substantially smaller files.
