Why convert WAV to MP3
A WAV file stores sound with no compression at all. That makes it very accurate, but also very large.
MP3 squeezes the same sound into a file that is usually 5 to 10 times smaller, so it is much easier to email, message or upload.
Choosing your MP3 quality
Kbps stands for kilobits per second. A higher number keeps more sound detail, and also makes a bigger file.
128 kbps works well for spoken word. 192 kbps is the default for stereo files and is a good match for music. 320 kbps is the highest MP3 setting.
This tool also reads other formats
Besides WAV, this converter reads M4A, MP3, AAC, AIFF and FLAC files, plus the sound inside a MOV or MP4 video.
If you later need to go back the other way, try MP3 to WAV.
Good to know before you start
This tool handles one WAV file at a time, up to 2 hours long. It checks your file first, so it never freezes partway through.
It works in modern browsers on iPhone, iPad, Android phones, and Mac or Windows computers, including Chrome, Safari and Edge.
Who this is for
Musicians and podcasters often have a big WAV export from recording software. So do people who recorded on a digital voice recorder. If your email or upload form will not take a file this large, convert it here. Once you have the MP3, you can also try audio to text to get a transcript.
Used by recruiters, executives, consultants, and more.
