What you want to findWhat to select
Several versions of the same shotChoose the similarity check. Compare the images in each group before selecting extras.
Identical image dataChoose the exact duplicate check. In the library, this skips edited photos, Live Photos and assets made of multiple files.
The best frame from a burstChoose the burst check with the System Photos Library as the source.
Pictures that take up spaceChoose the large-file check for a size in MB, or the high-resolution check for a pixel count.
Shots you might retakeCheck for blur, closed eyes, blank frames or exposure problems. An intentionally dark shot can appear here too.

Start the scan. All Cleanup Checks runs the categories together and includes the slower closed-eye check. For a quick comparison of one shoot, start with the similarity check alone.

Review before removing

Open a group and compare focus, expression and framing. Review any smart selection before confirming. When the source is the library, Delete from Photos removes the selected library items. With iCloud Photos enabled, that deletion also syncs to other devices.

The cleanup scan uses what’s available on this Mac and does not download iCloud originals. A photo can be visible in the library and still be skipped by an exact-duplicate or file-size check.
