About WAV to MP3
WAV files provide the highest possible audio quality because they are uncompressed, but this comes at the cost of very large file sizes. MP3 uses sophisticated psychoacoustic modeling to remove sounds the human ear can't easily hear, drastically reducing file size (often by 90%) while maintaining excellent clarity.
Our tool runs Client-Side. By using the `lamejs` encoder, your browser performs the math required to compress the audio. This ensures your private recordings stay on your computer and never touch a remote server.

- Convert: Click "CONVERT TO MP3". The browser will analyze the audio waveform and encode the MP3.
