Are my audio files uploaded anywhere?

No, audio conversion happens entirely in your browser using local processing.

What audio formats are supported?

Common formats like MP3, WAV and OGG are supported for conversion, depending on the specific tool.

There's no fixed limit, but very long files depend on your device's available memory to process smoothly.
