ShutterSlim uses AI to find similar photos in your Photos.app library and recompresses oversized videos—so you reclaim gigabytes of space without losing the moments that matter. You review every suggestion before anything is deleted.
Burst mode shots. Multiple takes of the same scene. Slight variations you'll never look at twice. Over time, these pile up—wasting gigabytes of storage and making it harder to find the photos that actually matter.
Uses Apple's Vision framework to create neural network fingerprints—not just filename or timestamp matching.
Suggests the sharpest photo with the best composition, face quality, and resolution—but you make the final call.
Nothing is deleted without your approval. Review every group, then confirm before anything is removed.
Smart caching means the first scan takes minutes, but future scans take seconds.
Scan your entire library, specific albums, or folders. Clean up vacation photos without touching everything else.
Modern HEVC re-encoding can shrink old videos by 70–90% with no visible quality loss. Compare before and after side-by-side, then replace originals only when you're satisfied.
Choose an album, folder, or your entire Photos.app library. ShutterSlim analyzes every locally-stored photo using AI to find visually similar images and groups them together.
See groups of similar photos side-by-side with quality scores. The AI pre-selects the best photo in each group, but you have full control to override any decision.
Review your trash before deletion. See exactly how much space you'll free. Deleted photos go to Photos.app's Recently Deleted for 30 days—just in case.
When you need to see every detail, enter fullscreen mode. Compare photos at full resolution with keyboard shortcuts for lightning-fast decisions.
Videos shot years ago use codecs that waste space on modern Macs. ShutterSlim re-encodes them with HEVC, often shaving 70–90% off the file size. Review every result with a side-by-side player before replacing the original—and the original only goes to Photos.app's Recently Deleted, so it's recoverable for 30 days.
