About this tool

This converts WAV audio into MP3. A WAV file is uncompressed — CD-quality stereo uses about 10MB per minute — so it is heavy to email, upload or store. An MP3 at 192 kbps uses about 1.4MB per minute and sounds the same to most listeners.

How to convert WAV to MP3

  1. 1.Choose the WAV file.
  2. 2.Pick a bitrate — higher keeps more detail and makes a bigger file.
  3. 3.Press Run and wait for the job to finish.
  4. 4.Download the MP3.

When people use it

Sharing a mix or a demo

Send a track as a file small enough to email or message.

Recorder and interview files

Field recorders and some voice apps save WAV. MP3 makes those files easy to store and share.

Uploading to websites

Many site builders and podcast hosts accept MP3, and some cap file sizes well below what a WAV needs.

What it will not do

Worth knowing before you upload, rather than after.

  • MP3 is lossy: some detail is discarded to save space, and the WAV cannot be rebuilt from the MP3. Keep the original if you might edit it again.
  • The 100MB free limit applies to the WAV you upload — roughly 9 minutes of CD-quality stereo.

Questions

How do I convert WAV to MP3?

Choose the WAV file above, pick a bitrate, and press Run. Download the MP3 when it is ready.

How much smaller will the MP3 be?

For CD-quality stereo WAV, about 7 times smaller at 192 kbps and about 11 times smaller at 128 kbps. WAV files at other sample rates or bit depths change the ratio.

Will I hear a difference?

At 192 kbps and above, most people cannot tell the MP3 from the WAV in normal listening. For mastering or further editing, keep the WAV.

Is it free?

Yes — free, no account, no watermark, for WAV files up to 100MB.

What happens to my file?

Your upload goes to private storage that is never public and never listed, and only the anonymous session that created the job can read it. The original file is deleted as soon as processing succeeds. The result stays available for about 90 minutes, and you can delete everything immediately with the Delete now button.
