Audio utilities that respect your privacy

Audio files from different sources often have inconsistent volume levels or come in formats that aren't universally supported. These tools help you normalize volume and convert between formats without uploading your files to any server.

Audio Normalizer — Peak normalization analyzes your WAV or MP3 file and adjusts the volume so the loudest moment reaches full scale (0 dB). This is ideal for making podcasts, voice recordings, and music tracks consistent.

WAV to MP3 Converter — Convert uncompressed WAV files to MP3 with your choice of bitrate (128–320 kbps). A typical 3-minute WAV file shrinks from ~30 MB to ~4 MB at 192 kbps, with quality most listeners can't distinguish from the original.

All tools run entirely in your browser via the Web Audio API and a JavaScript MP3 encoder. No audio data is ever transmitted to a server.
