About this option

WAV stores audio uncompressed, so recordings and exports take huge amounts of space. MP3 shrinks them to roughly a tenth while sounding nearly identical to most ears. This page opens the converter on MP3 at 192 kbps.

When to use it

  • A voice memo, mix or export is too large to email or upload
  • A device or platform doesn't accept WAV files
  • You are archiving recordings and want to save disk space

How to use it

  1. 1Drop your WAV file — MP3 is already selected as the output
  2. 2Click Convert and wait for the engine to process the file

Frequently asked questions

How much smaller will the MP3 be?

Typically about 10% of the WAV size. A 50 MB WAV becomes an MP3 of around 5 MB at 192 kbps.

Does MP3 sound worse than WAV?

MP3 is lossy, but 192 kbps is difficult to distinguish from the original for most listeners. Keep the WAV if you plan to edit the audio further.

Is my recording uploaded?

No. The conversion runs in your browser; only the converter engine itself is downloaded the first time you use it.
