iCloud photos

When you delete a photo or video from Photos on iCloud.com, it’s also deleted from all of your devices with iCloud Photos turned on. If you change your mind, you have 30 days to recover it before it’s permanently deleted.

I hope this helps!

You can also recover photos and videos you deleted in the last 30 days in the Recently Deleted folder of the Photos app on any computer, iOS device, or iPadOS device that has iCloud Photos turned on.
