MP3, WAV, M4A/AAC, FLAC, Ogg and WebM audio files are accepted when their codec is supported by your browser. A file with an unsupported codec shows an error on its row.

Can I convert a batch?

Are audio files uploaded?

No. Conversion runs in your browser. Encoder code is downloaded from this site only when needed; the files remain on your device.
