  1. 01

    Choose your file

    Select one file or a batch in the indicated input format.

  2. 02

    Adjust the result

    MP3 is lossy. Higher bitrates generally retain more detail and produce larger files. Sample rate and channels are preserved where supported; the MP3 encoder may adapt an unsupported source sample rate. Your original WAV is unchanged.

  3. 03

    Process and download

    Start processing, then play or download the result. Files are processed one at a time.

Frequently asked questions

Which MP3 bitrate should I choose?

192 kbps is a practical starting point. Use 128 kbps for smaller files or 256–320 kbps when retaining detail matters more than size.

Does WAV to MP3 reduce quality?

Yes. MP3 discards audio information. Keep the original WAV if you expect to edit the recording later.
