PhotoSweeper
A native Mac duplicate-photo cleaner that scans Apple Photos, Lightroom Classic, Capture One, folders, and external drives—grouping exact copies and visually similar shots so you can reclaim disk space without blind bulk deletes.
PhotoSweeper from the Overmacs team targets photographers and everyday Mac users whose libraries balloon with burst series, edited variants, RAW+JPEG pairs, and forgotten imports. The comparison engine analyzes image content, not just filenames, with adjustable similarity thresholds for duplicates, near-duplicates, and timed burst sequences. Results appear in side-by-side groups; Auto Mark rules pick keepers by resolution, file size, date, folder, Quality Score, or custom logic, while locked photos stay safe from removal.
Typical Mac workflow
Point PhotoSweeper at your Photos library or a folder of vacation RAWs, run a similarity scan, review groups in One-by-One or Face-to-Face modes, then mark extras for removal. Deletions are conservative: files go to the Trash, Lightroom shots are flagged Rejected, and Photos items land in a recovery album—not instant permanent erase. Version 5.4 added AI Quality Score badges for smarter Auto Mark; 5.5 refined pro workflows with XMP sidecar metadata, better Adobe DNG reads, improved Lightroom previews, and import options to skip hidden Photos items or rejected Lightroom picks. The app runs natively on Apple silicon, supports HEIC, RAW, PDF, and many video formats, and scales to very large libraries.
PhotoSweeper is sold on the Mac App Store (about $14.99) with Family Sharing; a trial is available from the developer site. It requires macOS 10.15 or later and is localized in English, French, German, Italian, Russian, Spanish, and Ukrainian. The developer states no analytics data collection on the App Store listing.
Version 5.5.4
Build 5.5.4 sits on the 5.5 feature line, but Overmacs has not published separate release notes for 5.5.4 as of this writing—the Mac App Store still lists 5.5.3 (May 7, 2026) with the 5.5 changelog. Documented 5.5 improvements include XMP sidecar metadata support, improved DNG handling, better Lightroom preview import, filters to ignore hidden Apple Photos or rejected Lightroom images, and general bug fixes. Treat 5.5.4 as a minor maintenance build in that line unless the vendor posts a dedicated note.
