Are online converters safe?

Is FreeConvert safe?

FreeConvert converts files on its own servers, so your file is uploaded first. Its privacy policy says uploads are stored on Amazon Web Services in Ireland, deleted automatically after 8 hours, and not viewed by its staff without your written consent unless a legal procedure requires it. Whether that's safe enough depends on the file: for up to 8 hours, a copy sits on a server you don't control.

Questions

FreeConvert is a working service with paid plans, a published privacy policy, and terms of use. Being legitimate and being right for a private file are different questions: any converter that runs on a server needs your file uploaded to it.

Its privacy policy says uploaded files are automatically and permanently deleted after 8 hours, and that you can delete them yourself before then.

Its privacy policy says it does not access or view your files, except with your explicit written consent or when a legal procedure requires it.

Yes. Mastershot converts video in your browser on your own device. The file is read from your disk and the result is saved back to it, with nothing sent to a server.
