Compress WAV to MP3 Online

WAV compression reduces the enormous file sizes typical of uncompressed audio recordings. Standard 16-bit 44.1kHz stereo WAV files consume about 10MB per minute, and professional 24-bit 96kHz recordings are even larger. Re-encoding to MP3 achieves roughly a 90% size reduction with quality that satisfies most listeners.

Bitrate selection controls the trade-off between file size and audio fidelity. 192kbps preserves most of the source detail and is a safe default for music. 128kbps is the sweet spot for general listening and matches typical streaming quality. 96kbps and lower are appropriate for speech, podcasts, and voice memos where size matters more than musical nuance.

Musicians compress studio recordings for sending to collaborators. Podcasters convert WAV recordings to distribution formats. Audio engineers create compressed versions for client review. Sound designers reduce asset sizes for game and app development. Archivists create space-efficient versions of lossless recordings for sharing.
