How to delete duplicate photos from iCloud

Lately, I noticed that my iCloud storage was almost full, and I kept getting those annoying pop-ups asking me to upgrade my storage plan. I decided to take a look at what was taking up so much space—and to my surprise, it was mostly my photos. I've had iCloud Photos turned on for a few years now, and over time, I've clicked tons of pictures—especially during family vacations, festivals, and random everyday moments.

As I was scrolling through my photo library, I realized I had so many duplicates—photos taken back-to-back, burst shots, edited versions of the same picture, or the same image saved from WhatsApp and again from my camera roll. It was just cluttered. I wanted to clean it up and get rid of the duplicates to free up space, but I was really confused about where to start.

I didn't want to delete something important by mistake, and I wasn't even sure if deleting from iCloud would remove the photo from my iPhone too.
