By default, iTunes or iCloud will sync your photos in bulk, with little control over the process, and no export options.
Mac users who do not sync their photos via iCloud can delete their photos using their Mac's native Photos app, but there is no equivalent Apple software for Windows users.
With iMazing, it's easy to delete single or multiple photos from your iPhone, iPad, or iPod from your Mac or PC computer without syncing or going through the cloud.
Anyone who wants to:
Download and install iMazing.
To delete photos from your iPhone, iPad, or iPod Touch:
Launch iMazing and connect your device.
In the left sidebar, select Camera. To view your most recent photos, you may need to refresh your data.
In the main window, select the photo(s) you want to delete.
In the bottom toolbar, click the Delete button. This will open a confirmation dialog box.
In the dialog box, click Yes to start the delete operation.
