Security FAQ
Are my files really not uploaded?
Yes, absolutely. You can verify this by disconnecting from the internet after the page loads - conversions will still work because everything runs locally in your browser.
Is my data stored anywhere?
No. We don't store your audio files, conversion history, or any personal data. Once you close the browser tab, all temporary data is cleared.
Can I use this for sensitive audio files?
Yes. Since all processing happens locally on your device, Audio Converter is safe for sensitive or confidential audio files. Your files never touch our servers.
