WAV to MP3

WAV files are uncompressed and large. As MP3 they need a fraction of the space.

How it works

  1. Open your WAV file.
  2. Choose the quality.
  3. Click "Save as MP3".

Questions and answers

How much smaller does the file get?

At normal CD quality, an MP3 at 192 kbit/s is about seven times smaller than the WAV file.

Can you hear the difference?

MP3 stores sound with some loss. At 320 kbit/s the difference to the original is small, at 128 kbit/s it is easier to hear.

Is my file uploaded?

No. Cutwisp processes the file inside your browser. It is never sent to a server.

Does it cost anything? Is there a watermark?

Cutwisp is free, and it doesn't add a watermark.
