# Convert WAV to MP3

Convert WAV to MP3 right in your browser — free, private, nothing is uploaded. Pick a bitrate (32–320 kbps) and shrink the file dramatically.

WAV stores raw, uncompressed PCM samples — the audio equivalent of a bitmap. Files are huge, but every editor, DAW and operating system opens them without a second thought.

MP3 is the most widely supported audio format there is — a lossy codec that shrinks audio to a fraction of its uncompressed size and plays on virtually anything with a speaker.

Converting WAV to MP3 trades a sliver of fidelity for a dramatic drop in size: a WAV recording that hogs storage becomes an MP3 file you can email, message or stream. It's the classic move for sharing voice memos, publishing spoken audio and fitting a music library onto a phone.
