Why convert WAV to MP3?

WAV is a format that stores audio uncompressed: studio recordings, audio recorders and many editing programs produce WAV files. The quality is high, but the files are very large; one minute of stereo WAV takes up about 10 MB. A file like that is hard to send by email, share in a messaging app or keep on your phone.

The WAV to MP3 tool converts your recording to a high-quality MP3 (about 190 kbps, variable bitrate). The file usually shrinks to around a seventh of its size, and the difference is often inaudible.

You can upload one WAV of up to 95 MB at a time. Recordings above 48 kHz are reduced to 48 kHz, and multichannel recordings are mixed down to stereo.

How to convert WAV to MP3 in 3 steps

  1. Choose your WAV file: Drag your recording onto the area above or click to select it (up to 95 MB).

  2. Convert: Click “Convert to MP3” and follow the progress live.

  3. Download the MP3: The file has the same name as your WAV. It is deleted from the server after about 10 minutes.

When is it useful?

  • Sharing recordings: Getting WAV files from an audio recorder or microphone down to a size you can send by email or in messaging apps.

  • Music and demos: Sending listening copies of studio or home recordings to bandmates and listeners as MP3s.

  • Podcasts and voice-overs: Converting edited WAV recordings to MP3 before uploading them to publishing platforms.

  • Archiving and saving space: Shrinking old WAV recordings that take up space on your phone or computer.

  • Compatibility: Preparing MP3s for car systems, older music players and application portals that don't play WAV.

04

Quality, size and limitations

  • High quality: The MP3 is encoded with a variable bitrate of about 190 kbps; the loss is barely audible in music and speech.

  • Much smaller file: One minute of stereo WAV is about 10 MB, while the same length of MP3 is usually around 1.5 MB. For an even smaller file, use the Compress Audio tool.

  • Compatibility: Sample rates above 48 kHz are reduced to 48 kHz and more than two channels are mixed down to stereo.

  • Limitations: One file at a time, up to 95 MB (about 9 minutes of stereo WAV) and 3 hours.

Privacy and automatic deletion

Your files are sent to our server over an encrypted HTTPS connection. The original file you upload is deleted as soon as processing finishes. The result file is kept only briefly so you can download it: an automatic clean-up job runs every minute and permanently deletes files older than 10 minutes. We therefore recommend downloading your result as soon as it is ready.

The download link only works for the user or browser session that started the job, and your files are never shared with other users. Our job log stores only details such as the file name, size and type of operation, never the file itself.

Frequently Asked Questions

Is converting WAV to MP3 free?

Yes. The tool is free and works without an account. Guests have a 24-hour usage allowance per tool; a free account lets you convert more files.

How small will the MP3 be?

Usually between a seventh and a tenth of the size of the WAV. One minute of stereo WAV is about 10 MB; the same length of MP3 is about 1.5 MB.

Does converting to MP3 reduce quality?

MP3 is a lossy format, but at about 190 kbps the difference is inaudible to most listeners. If you're going to keep editing the recording, keep a copy of the WAV.

How do I convert a WAV file larger than 95 MB?

95 MB is about 9 minutes of stereo WAV. You can split longer recordings into parts in your editing program, or export them as mono to halve the size.

Which types of WAV are supported?

16-, 24- and 32-bit PCM and floating-point WAV files are supported. Recordings above 48 kHz are reduced to 48 kHz.

Are my files stored?

No. The WAV you upload is deleted from the server as soon as the conversion is finished. The MP3 is kept only so you can download it and is deleted automatically within about 10 minutes.
