Can I convert multiple ALAC files at once?

Yes — batch conversion is supported. Add as many ALAC files as you like and convert them to AIFF in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
