About this tool
WAV files store uncompressed audio, so a few minutes can take tens of megabytes. Converting to MP3 typically makes them many times smaller while sounding very close to the original at 192 kbps or above. The conversion runs on our server with FFmpeg's LAME MP3 encoder, and your files are deleted as soon as the result is sent.
Frequently asked questions
How much smaller will the MP3 be?
A CD-quality stereo WAV uses about 1,411 kbps. At 192 kbps the MP3 is roughly 7 times smaller; at 128 kbps about 11 times smaller.
Which bitrate should I use?
128 kbps for speech, 192 kbps for most music, 320 kbps when you want the highest MP3 quality.
Is WAV to MP3 private?
Your file is uploaded over an encrypted connection and processed in a private temporary folder on our server. The uploaded file and the result are deleted from the server as soon as processing finishes — whether it succeeds or fails — and the result is sent straight to your browser. If an upload is interrupted part-way, its temporary data is removed automatically within about 30 minutes. We do not keep copies.
