Can you have multiple Photos libraries on an iPad?

Hello Tom Wolsky,

Thanks for your post to Apple Support Communities. We understand you are asking about creating more than one Photo Library on your iPad. There isn't a way within the iPadOS to do so that we're able to recommend or advise on. We do appreciate hearing suggestions from our users and would encourage you to submit this feedback at our official online form:

Product Feedback - Apple

All the best.

Hey there Tom,

You can use iCloud Photos to sync the same photos to your iPad and Mac, along with other options listed here: Transfer photos and videos from your iPhone, iPad, or iPod touch to your Mac or PC

If you're looking to do something completely different than what is listed in the link above, we'd also recommend submitting feedback for consideration using the link provided earlier.

Cheers!

The ONLY way I know how to do that is to plug the iPad into a Mac, wait for thr Photos app to launch and just import your whole iPad Photo library to the Photos app/Library on your Mac.

This will, of course, just add to whatever Photo library your Mac is currently linked to.
