PhotoSweeper for Mac

Overview of the app

PhotoSweeper for Mac is a tool designed to find and remove redundant images from your collection. It quickly scans large libraries and flags photos that are identical or very similar — including files that were altered in external editors — helping you reclaim disk space and keep your photo library organized.

Core capabilities

• Rapid duplicate detection that handles very large libraries with minimal delay.
• Multiple comparison algorithms (six distinct methods) to catch near-duplicates as well as exact copies.
• Native compatibility with popular photo libraries and editors so images from different sources are handled correctly.
• Recognition of photos that have been edited in external programs (for example, layered or retouched images) and identification of matches among them.
• In-app preview tools plus drag-and-drop management, and the ability to view ratings and color labels for quick selection.
• A clean macOS-style interface that integrates smoothly into the OS.

Recent improvements

• Improved comparison engine: enhanced matching logic, better performance and reduced memory footprint for smoother scanning of big collections.
• Added video handling: you can include video files from drives or libraries to locate duplicate movies.
• Expanded image inspection: a detailed info panel now shows a larger preview, histogram and full metadata (EXIF, IPTC, etc.).

Earlier enhancements

• Auto-placement rules: preferences let you define which items are automatically moved into the review Box.
• PDF comparison: documents are compared by their first page to detect duplicate PDFs.
• Direct Aperture and iPhoto access: drag items from the Media window to import photos straight from those libraries.
• Lightroom integration: drag from the Media window to bring in pictures from a Lightroom catalog.

Practical tips and caution

While PhotoSweeper is generally effective at identifying true duplicates, no automatic tool is perfect. Always keep a backup of your photo library before performing mass deletions and review matched groups carefully before confirming removal. Use the preview, ratings and metadata views to ensure you preserve originals you want to keep.

Final note

Overall, PhotoSweeper is a powerful option for cleaning up duplicated images and videos on macOS — fast, flexible, and packed with features to help you manage and declutter your media collections.
