Audio processing: Your WAV is decoded and converted in the browser. An MP3 encoding library is loaded from a CDN, so an internet connection is needed initially. PCM and floating-point WAV files supported by your browser can be converted; some specialized WAV codecs may not work. MP3 is a lossy format, so some audio detail is discarded.
How to Convert WAV to MP3
Upload your WAV recording, choose the desired MP3 bitrate, and select mono or stereo output. Click Convert WAV to MP3, then preview and download your converted file.
WAV audio commonly stores uncompressed samples, which can require substantial disk space. MP3 encoding uses compression to create smaller files at a selected bitrate. The final size depends primarily on the duration, number of channels, and bitrate selected.
