Review apparent photo duplicates before deleting anything

Last materially reviewed 2026-09-28

Quick answerTreat a duplicate detector as a shortlist, not permission to remove the only high-quality or meaningfully edited version.
What to know

Separate exact copies from similar images

Two images may look identical while differing in resolution, crop, metadata or provenance. A burst sequence may contain a subtly better expression. An exact duplicate can still be the only independent copy in another location. Decide whether you are reducing repeated files inside a master set or accidentally reducing the number of protected copies.

What to know

Use a quarantine stage

Move suspected duplicates only within a copied working set or mark them for review without deleting. Keep a record of the reason and retained counterpart. Do not empty a cloud trash area as part of the first cleanup. A temporary quarantine is useful only if it is clearly labelled and the accepted master remains independently protected.

What to know

Check the matching rule

If you use a local comparison tool, understand whether it compares bytes, names, dimensions or visual similarity. Each answers a different question. A matching filename is weak evidence; a byte match shows identical file content but does not decide where you should keep recovery copies. This site performs no duplicate detection and requests no photo uploads.

What to know

A fictional decision

A scan appears as TIFF and JPEG. They show the same subject but are not interchangeable duplicates. Retain the source scan and the convenient viewing copy with distinct roles. Two byte-identicalJPEGs inside the same accepted folder may be redundant, but a matching JPEG on a separately stored backup disk serves a protection role. Do not count it as clutter simply because its content matches.

What to know

Write the retention reason

For a proposed removal, record the retained counterpart and why the discarded item adds no distinct source, edit or protection role. If you cannot name the counterpart, pause the removal. Keep an independent reference copy through the review period. This small discipline helps distinguish redundant files inside one collection from deliberately repeated files that make the collection recoverable after a different kind of failure.

Continue when useful

Next: Originals and copies

Preserve the best available source and label derivatives; the biggest file or prettiest preview is not automatically the original.
