About WAV to MP3 Converter — Free Online Tool
WAV to MP3 Converter encodes an uncompressed WAV file as MP3 at a bitrate you pick, anywhere from 32 up to 320 kbps.
libmp3lame is driven at a constant bitrate, defaulting to 192 kbps; nothing here inspects the WAV and decides a number on your behalf. The size drop is dramatic because of what the input was — stereo 44.1 kHz 16-bit PCM carries about 1,411 kbps, so even the 320 kbps setting is a small fraction of it. The step is lossy and it is one-way: keep the WAV if it is your master, because converting the MP3 back will not recover what this pass removes.
Encoding takes place in a worker thread in your browser, so a studio session or a field recording stays on the machine it was made on. Nothing is uploaded and no copy is retained.
Sending a mix to someone who only needs to listen to it, reclaiming the space a folder of session WAVs occupies, putting a long recording on a phone without filling it, and attaching audio to a message that would reject the original.
