Is CloudConvert safe?
Yes, CloudConvert is a legitimate converter, run by Lunaweb GmbH in Germany. The catch is that it converts files on its own servers, so yours is uploaded. Its privacy policy says files are stored temporarily on servers in Germany, or in the US if you're in the US, deleted within 24 hours at the latest, and processed by machine with no person looking at them. Its security page says the company holds ISO 27001 certification. Your file still leaves your device for up to a day.
