Audio Converter
Convert audio files to universal WAV format in your browser.
An honest note on formats. Your browser can reliably decode most audio (MP3, M4A, AAC, OGG, FLAC, WAV) and this tool re-encodes to WAV, which plays everywhere. Producing compressed MP3/AAC/OGG/FLAC in-browser requires a large encoder that would slow the page for everyone; we've chosen not to ship that bloat. To shrink the WAV afterward, use the Audio Compressor. If you specifically need MP3 output, a desktop tool like Audacity (free) is the right choice.
How it works
The file is decoded with the Web Audio API and written out as a standard 16-bit WAV — locally, nothing uploaded. WAV is lossless and universally compatible, making it the safest interchange format.
