WAV vs MP3

WAV stores every sample uncompressed. MP3 removes sounds you cannot hear; at 192–320 kbps the difference is inaudible for nearly everyone, at a fraction of the size.

Limitations

Up to 60 minutes and 500 MB per file.
Which input formats open depends on your browser: Chrome and Edge read the most formats.

Privacy

Files you choose are read into your browser’s memory and processed on your device; they are not uploaded to a server. Temporary download links are released after use, and the offline cache never stores your documents. More about privacy and limits.

Frequently asked questions

What is the best bitrate for WAV to MP3?

320 kbps for music you want to keep at the highest quality, 192 kbps for everyday listening, 128 kbps or less for speech.

Are my files uploaded?

No. The audio is decoded and processed in your browser, so recordings and videos never leave your device.

Is it free?

Yes – free with no signup, no watermark and no daily limit.

How long can a recording be?

Up to 60 minutes per file (and 500 MB). The whole recording is held in your device’s memory while it is processed, so very long files need a computer rather than an older phone.
