A: Yes, our bulk converter is completely free to use with no hidden fees, subscriptions, or file limits.

Q: Are my uploaded audio files safe?

A: Absolutely. Your files are processed entirely on your device using JavaScript. Nothing is stored, saved, or uploaded to an external server.

Q: Should I choose MP3 or WAV format?

A: Choose MP3 if you want smaller file sizes that are easy to share, stream, or store. Choose WAV if you require lossy-free, original audio quality for video editing, music production, or podcasting.
