Why ZIP instead of individual files?

Modern browsers block multiple downloads triggered from a single action. ZIP is the cleanest workaround.

Does it preserve metadata?

Yes. ID3 tags in the source carry over to the new MP3 where possible.

What if one file fails?

The rest of the batch continues. Failed files are listed with their error so you can retry individually.
