Is Zamzar safe to use?

Short answer

Zamzar uploads your files to its servers.

When you use Zamzar, your documents are transmitted over the internet to third-party servers for processing. You are trusting their retention, security, and privacy policies with your data — and once a file is uploaded, you cannot verify what happens to it.

The private alternative

Brevio runs every tool entirely inside your browser. Your files are never uploaded — they never leave your device. No account, no server, no retention. You can verify it yourself in the browser network tab.
