What audio formats can I cut?

You can cut MP3, WAV, OGG, FLAC, AAC, M4A and most other audio formats that your browser supports. The output is always saved as WAV, which is lossless.

Is my audio file uploaded to a server?

No. All processing is done entirely inside your browser using the Web Audio API. Your file never leaves your device.

Why is the output a WAV file?

The Web Audio API decodes audio into raw PCM data which is re-encoded as WAV — a lossless format. WAV files are universally compatible and require no additional encoding libraries.
