Are my files uploaded to a server?

No. Every file you select is processed entirely inside your browser using your device's own memory. Nothing is uploaded, stored or shared, so customer documents never leave your computer or phone.

Is there any limit, watermark or sign-up?

No. The tool is free, unlimited and needs no account. Output files carry no watermark of any kind.

Will it look exactly like Word?

The text, headings, lists and tables are kept, but images, exact fonts and complex layouts are not reproduced. This is a real text conversion, not a screenshot.
