How do I quickly find and delete duplicate photos on my iPhone?

Let's be honest with each other. Using Windows Explorer + Manual Sorting is technically a free method for how to delete duplicate photos on iPhone.

So you'd have to copy everything to your PC first. Once the photos are safely on your hard drive, here's how to delete duplicate photos on iPhone:

1. Open the folder in Windows Explorer

2. Switch to Large Icons or Extra Large Icons view so you can actually see what each photo looks like

3. Sort by Date Taken or Date Modified to group similar photos together

4. Scroll through hundreds or thousands of photos, one by one

5. Manually spot the duplicates – "Oh, that's the same photo of my cat, but one has slightly brighter lighting"

6. Select the copy you want to delete (Ctrl+click to pick multiple files)

7. Move them to the Recycle Bin

8. Repeat for every set of duplicates

This works if you have maybe 20-30 photos. But if your iPhone has been collecting years of camera photos, screenshots, and shared images like you mentioned, manual sorting is going to take hours.
