About this tool
AudioCharger's converter reads almost every common audio and video container (MP3, WAV, FLAC, AAC/M4A, OGG, Opus, WebM, MP4, MOV, MKV) and writes MP3, WAV, FLAC, M4A, OGG or WebM. Conversion runs on your device with WebCodecs and WebAssembly, so even large files never upload anywhere.
All processing happens locally in your browser, ensuring complete privacy for your recordings and music.
