Are my audio files sent to a server?

No. "Convert an audio file" processes your files directly in your browser: they stay on your device.

Is there a size limit?

The limit mostly depends on your device's memory. Typical audio files (a few hundred MB) go through without any issue; processing takes roughly the length of the audio.

Do I need to create an account?

No. The tool is ready to use right away. A free account is only useful for finding your history again.
