Summary. To summarize, turning off iCloud Photos will not delete existing photos from iCloud. However, they may be deleted from iPhone/iPad depending on the above two settings. If you accidentally turn off iCloud Photos, don't worry for your data is safe on iCloud even if it disappears from your iPhone/iPad.
If you want to remove photos and videos from all your iOS devices, your Mac, and iCloud.com, you can delete them in the Photos app. You can recover your photos and videos from the Recently Deleted album for 30 days.
Now you can use Duplicate File Finder to remove duplicate photos.
(I've omitted the sender's name so as not to single them out!) Just to be clear: If you delete a photo or video from Photos in iOS or macOS and iCloud Photo Library is enabled, it will delete it everywhere, even if you have full-resolution downloads turned on with Photos for macOS.
Disable iCloud Photos on All Devices Available as 'Disable and Delete,' the feature will necessarily remove all your photos and videos saved in iCloud and free up storage space on iCloud.
On a Mac: You can set up cloud sync from the Photos app. Once you have the app open, head to Photos > Preferences > iCloud. There, select the checkbox for iCloud Photo Library. You'll also find this setting under System Preferences > iCloud > Photos > Options.

Apple gives users 5GB of free iCloud storage space for all possible purposes. However, all Mac owners may face the problem of duplicate photos filling up their storage space. Day after day, these duplicate and similar photos take up a lot of space on your cloud storage.
The only real difference here is that you'll need to move to iCloud Photos. If you recently created an Apple ID, you'll notice that My Photo Stream isn't an option. Only iCloud Photos gives you access to all your photos and videos from all your devices, superseding the abilities of My Photo Stream in most cases.
You can set up the same automatic syncing on the Mac, too. To do that, go to Apple menu > System Preferences > Apple ID > iCloud > check Photos. Then go to Photos app > Photos menu > Preferences > check iCloud Photos.
