Yes. The tool is provided for free use in the browser.
Are my files uploaded?
The conversion interface is designed to process files locally in the browser rather than intentionally uploading them to a website server.

Not always. Conversion quality depends on the source file, fonts, layout, images and browser processing. Review the output before relying on it.
