About WAV to MP3

Compress large, uncompressed WAV (PCM) audio files into lightweight, universally compatible MP3 files. Uncompressed WAV files often take up tens of megabytes; converting them to MP3 can reduce file size by up to 90% while preserving excellent acoustic fidelity.

Processing is performed entirely in your browser using the WebAssembly-compiled LAME audio engine. No files are ever sent to a remote server, keeping your voice recordings, podcast stems, and audio tracks completely private. Choose your preferred bitrate to fine-tune the balance between compression and fidelity.

How to use WAV to MP3

  1. Drop your uncompressed WAV file into the converter box.
  2. Select your desired MP3 bitrate (192 kbps is recommended for general listening; 320 kbps for maximum fidelity).
  3. Click Convert to compress the WAV audio into MP3 using the client-side LAME encoder.
  4. Listen to the playback preview and click Download to save your new MP3.
