About WAV to MP3 Converter

Convert WAV to MP3 in your browser. The file is decoded with the Web Audio API and re-encoded to MP3 with a pure-JavaScript LAME encoder, at the bitrate you pick (64–320 kbps). WAV is uncompressed (about 10 MB per minute in CD quality); a 192 kbps MP3 is roughly 7× smaller with near-transparent quality for most listeners. Everything runs on your device — nothing is uploaded.

Frequently asked questions

How do I convert WAV to MP3?+

Drop the file here. It is decoded in your browser and encoded to MP3 with the LAME algorithm — then you download the result. No upload, no account, no watermark.

Which bitrate should I choose?+

192 kbps is transparent for most music; 128 kbps is fine for podcasts and speech; 320 kbps is the maximum MP3 allows and best for archiving. Lower bitrates make smaller files.

Will I lose quality?+

MP3 is lossy, so some data is discarded compared with the lossless WAV original — at 192 kbps and above the difference is inaudible to most people.

Is my file uploaded?+

No. Decoding and MP3 encoding run entirely on your device, so private recordings stay private.
