Duplicate Cleanup
Family archives almost always collect multiple copies of the same photo — the original scan, a rescan after a better light, and a restored derivative. Nostalgia finds them automatically, compares quality, and merges the metadata into the best keeper so you don’t lose tags, albums, or favorites.
Group similar photos, keep the best one
Detect
Every uploaded or restored photo is fingerprinted with a perceptual hash so visually similar images can be grouped without relying on filenames or EXIF data.
Compare
Nostalgia scores each photo in the group on capture quality and recommends which version to keep — usually the sharpest, best-lit, highest-resolution scan.
Merge
Accept the suggestion and the absorbed copies are soft-deleted into Trash, while their tags, albums, favorites, and restored variants transfer to the keeper automatically.
What gets grouped and preserved
Exact duplicates
The same file uploaded twice, or two scans of the same print at the same resolution. Merged silently with no prompt.
Same-print rescans
A rescan that caught less glare or better color balance is recognized as the same photo. Nostalgia suggests keeping the stronger capture.
Restored derivatives
Restored versions stay linked to the original they came from, so merging never accidentally collapses a restored result into its source scan.
Metadata transfer
Tags, captions, album memberships, favorites, and version history all follow the keeper so you never lose organization work when you clean up.
Undo-friendly
Merged copies land in Trash with a 30-day recovery window. If the wrong keeper was picked, restore the alternate and redo the merge.
Scan-review integration
During scan sessions, possible duplicates are flagged inline before they clutter the library — so you clean up at the front door instead of after the fact.
Let the archive clean itself up
Duplicate Cleanup is on by default for every account — no setup, no extra credit, no separate tool to learn.
