Convert WAV to MP3 online
Shrink large WAV recordings into MP3 files that are easy to share, upload and play anywhere. Choose your bitrate, convert in batches and keep your audio private.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
Much smaller files
A minute of CD-quality WAV takes about 10 MB, while a 192 kbps MP3 takes about 1.4 MB. That makes MP3 the practical choice for email, podcasts, websites and phones.
Picking a bitrate
Use 128 kbps for speech, 192 kbps as a good default for music and 320 kbps when you want the highest MP3 quality. Keep your WAV as the master copy.
FAQ
Will I hear a difference?
At 192 kbps and above, most people cannot hear a difference on typical speakers and headphones.
Can I convert a whole folder?
Yes. Drop many files at once and download the results together as a ZIP.
Is my WAV uploaded?
No. The encoding runs on your own device.
What can you do with an audio converter?
Editors turn phone recordings into WAV files that every timeline accepts; podcasters export a small MP3 from a large master; musicians archive takes as lossless FLAC; and anyone stuck with a file a device refuses to play can switch it to a format that works everywhere.
