How to use Audio Converter
- Choose an audio file.
- Pick the output format: WAV or WebM.
- Click Process Audio to convert it.
- Download the converted file.
Honest limit: browsers can only encode WAV (PCM) and WebM (Opus) audio — they cannot encode native MP3, AAC or FLAC. This tool converts to real WAV or WebM and says so on the download.
