How to Find and Remove Duplicate Photos

Duplicates are rarely the same file twice. More often they are a burst of shots taken a second apart, a photo saved again from a chat app, an edited copy next to the original, or the same picture exported in two sizes. To your eyes they look the same; to a computer they are different files.

An exact duplicate is byte-for-byte identical and is safe to remove. A similar photo is different, even if only slightly: perhaps someone blinked, or the focus is a little softer. Those need a human decision, because the “worse” one is not always obvious.

Our photo cleaner compares a small visual fingerprint of each picture, so it can group near-identical shots even if their file names and sizes differ. It then suggests the sharpest picture in each group as the keeper. You can change the choice before anything is removed.

Look at faces first: open eyes and natural expressions beat everything else. Then check focus, by zooming in on the subject. Then look at framing. If two shots are equally good, keep the one with the higher resolution and remove the rest.

A website cannot delete files straight from your photo library, and that is a good safety net. Instead you get a cleaned copy to download and a checklist of the files to delete in your Photos or Gallery app. Back up first, delete the ones on the checklist, and then empty the recently-deleted area so the space is actually released.

Deleting the weaker shots straight after a photo session takes seconds and prevents the pile from forming. If that is not realistic, schedule a monthly review and let the tool do the first sort.
