WAV to MP3 Converter: limits and things worth knowing

• WAV is uncompressed, so the reduction is dramatic — typically around 90%. A three-minute CD-quality WAV is roughly 30 MB and becomes about 3 MB at 128 kbps.
• This is the one direction where the first encode happens from a clean source, so quality at a given bitrate is as good as MP3 gets. Keep the WAV as the master.
• For speech, 96-128 kbps mono is usually indistinguishable from the source. Music benefits from 192 kbps or more.
• If you need lossless compression instead, FLAC halves the size with no quality loss at all.

Is it private and secure?

Your privacy is built in. WAV to MP3 Converter runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
