Why file privacy matters

When you upload a document to a typical online converter, it travels across the internet to their servers, gets processed (and potentially stored, logged, or analyzed), then gets sent back. ConvertiZen eliminates this entirely. Your Word, PDF, or Excel file is converted on your own CPU, in your own browser sandbox, under your own control.
