how to delete duplicate photos from icloud

Hello karen3430,

Thanks for posting your question. I see you want to know about deleting duplicated photos in iCloud, and it sounds like you may be viewing your photos on the iCloud.com website.

To answer your question, there's not a tool that deletes duplicates photos specifically. Using the iCloud website, you can select and delete multiple photos at a time, which might help if you have a large amount to delete: Delete photos and videos on iCloud.com

"You can select a single photo or video or multiple photos and videos.

Select a single photo or video: Click it.

Select a group of adjacent photos or videos: Click the first one, then hold down the Shift key while you click the last one. You can also drag to enclose them within a selection rectangle.

Select a group of nonadjacent photos or videos: Command-click (on a Mac) or Control-click (on a Windows computer) the items you want to include.

Select all photos and videos in an album or folder: Press Command-A (on a Mac) or Control-A (on a Windows computer)."

If you'd like, you can always send feedback to Apple here: Product Feedback

As a side note, this resource has some helpful information about third-party duplicate removing tools: Using third-party apps to remove duplicate photos might damage your Photos for macOS library

Take care.
