Frequently asked questions
Is this WAV to MP3 converter really free?
Yes — free with no account, no watermark, and no length limit.
How much smaller will my file get?
Roughly 10× smaller: a 60 MB WAV becomes about a 6 MB MP3 at 128 kbps.
Does converting lose quality?
MP3 is lossy, so a little is removed — but at 128 kbps the difference is hard to hear for voice and most music.
Are my files uploaded to a server?
No. All processing happens locally in your browser using Web APIs. Your files never leave your computer — close the tab and nothing remains.
