Other WAV conversions

Private by design — no upload, no sign-up

This WAV to MP3 converter runs locally, using your own browser. Your files are never uploaded to a server, so they stay on your device from start to finish.

Are my WAV files uploaded to a server?
No. The WAV to MP3 conversion runs locally in your browser using your own device's CPU. Your files are never uploaded, never transmitted over the network and never stored on a server.
Is there a file size limit for WAV to MP3?
There is no imposed limit, because nothing is uploaded. The practical ceiling is your device's available memory, so very large files may be slower on older hardware.
Does it work offline?
Yes. Once the page has loaded, converting WAV to MP3 keeps working without a network connection, since the conversion happens entirely on your device.
Do I need to sign up or install anything?
No. There is no sign-up, no account and no software to install. Pick a WAV file and convert it to MP3 straight away.
Is converting WAV to MP3 free?
Yes, it is free to use, with no watermarks and no daily quota.
