Why it matters that files never leave your device

Audio files can contain sensitive content — voice recordings, meetings, personal music. Upload-based converters store your files on their servers, often for 24+ hours. Here, your WAV is decoded and re-encoded locally using the Web Audio API. Zero network transfer.
