Why nothing is uploaded. Every tool here runs entirely inside your own browser tab. The files you open and the lists you paste are read by your own device and never sent to a server — which matters, because the emails people convert are usually invoices, contracts, disputes and HR matters, and most online converters ask you to hand those to a stranger.
