    What makes an audio converter private?

    A private audio converter processes files inside your browser instead of sending them away first. That matters when the recording contains client material, internal meetings, interview audio, or anything else you would rather keep on the current device.

    It is a practical privacy choice, not a magic privacy guarantee. If the job can be done locally, there is simply less exposure than with a converter that starts by uploading the file.

    Why keeping conversion local matters

    In a local browser workflow, the source file stays on the device while you change format, bitrate, or channels. That is useful for sensitive recordings, but also for simple convenience when your connection is slow or the source file is large.
