Are my files uploaded to a server?

No. Conversion runs locally in the browser, so your files stay on your device during processing.

Which format should I use for sharing private recordings?

MP3 is usually the safest choice for compatibility. Use 96-128 kbps mono for speech and 192 kbps stereo for general listening.

Can I convert confidential interview audio?

Yes. This workflow is designed for local processing, which is useful when you want to avoid uploading source audio to an external service.

What makes an audio converter private?

A private audio converter processes files inside your browser instead of uploading them to a remote server first. That matters when you are working with recordings that should not leave your laptop, phone, or office network.

When private conversion matters most

Client work: convert draft voiceovers, interviews, and review files without sending them through third-party servers.
Internal recordings: keep meeting snippets, training audio, or notes on the local device.
Personal archives: convert family recordings and voice memos without creating cloud copies.
Fast turnarounds: avoid upload delays for large WAV or FLAC files.

Why local browser processing is useful

No upload queue: conversion can start immediately on the current device.
Less exposure: audio does not need to be transferred to an external storage system.
Better control: you decide format, bitrate, and channel settings before export.
Cross-platform: the same workflow works on desktop and mobile with a modern browser.

Practical output settings

Voice notes and interviews: MP3, 96-128 kbps, mono.
General sharing: MP3, 192 kbps, stereo.
Smaller modern files: AAC, 128 kbps, stereo.
Editing or archive copies: WAV or FLAC when you do not want additional compression loss.

Common privacy misunderstandings

Private does not mean anonymous hosting: if a tool uploads files for processing, it is not local-only.
Compressed does not mean safer: a smaller MP3 is still sensitive if it contains confidential audio.
Temporary files still matter: always download only the exports you need and manage them carefully on shared devices.
