Convert MP3 to WAV or WAV to MP3
Upload either an MP3 or a WAV file - this tool decodes the audio track in your browser and generates both a WAV (uncompressed) and an MP3 (compressed, 192 kbps) version, so you can download whichever format you actually need. Nothing is uploaded to a server.
How to use it
- Choose an .mp3 or .wav file, or drop it in.
- Press Convert.
- Download the WAV or MP3 version.
MP3 vs WAV, in short
WAV is uncompressed audio - larger files, but no quality loss, which is preferred for editing and archiving. MP3 is compressed - much smaller files at a small quality cost, ideal for everyday listening, sharing and storage. Converting WAV to MP3 shrinks the file size for sharing; converting MP3 to WAV gives you an uncompressed version that's friendlier for further editing in audio software.
Common uses
- Shrinking large WAV recordings down to MP3 for sharing or streaming
- Getting an uncompressed WAV from an MP3 for use in audio editing software
- Preparing audio files for software that only accepts one specific format
