Using lossy image format for preservation?

It's less about perfectly preserving the quality of the original and more about ensuring that the data remains decipherable.

Like if you're archiving something that contains charts, a pixel perfect image of the chart is no good if your device can't read the file format. But if it's a JPEG chances are you can still render and understand what it has despite any lossiness.
