PowerPhotos 3.4.4

PowerPhotos is a photo library management utility for macOS developed by Fat Cat Software, built to extend what Apple's built-in Photos app can do by letting users work with multiple Photos libraries at once, merge libraries together, and find duplicate photos across an entire collection. PowerPhotos requires macOS 14 (Sonoma) or later and is sold as a licensed application with free updates within a major version. A note on the requested version: official sources — including Fat Cat Software's own download page and TidBITS coverage — confirm 3.4.3 as the most recent publicly documented release at time of writing, with no official record found of a separate "3.4.4" version; this listing reflects the app's confirmed 3.4.x update line, most recently including 3.4.2's macOS 27 Golden Gate beta compatibility fixes and 3.4.1's crash fixes. What makes PowerPhotos distinctive is that it works directly with the Photos app's own library format rather than replacing it, giving users far more flexibility in how their photo collection is organized. Instead of being limited to a single, ever-growing Photos library, PowerPhotos lets users split photos across multiple libraries — for example, keeping one smaller library synced to iCloud while storing the bulk of a collection in separate, local-only libraries — and switch between or browse them without opening each one individually in Photos. Since PowerPhotos 3.0's April 2025 release, the app has also added batch photo metadata editing, advanced search across multiple libraries simultaneously, and a redesigned in-window photo viewer, on top of its long-standing library merging and duplicate-detection tools.

Launch PowerPhotos and add your existing Photos libraries so the app can access and manage them. Use the library switcher to browse and compare photos across multiple libraries without opening each in Photos. Run a duplicate search across one or more libraries, reviewing side-by-side matches before deleting unwanted copies. Merge libraries together when you want to consolidate multiple Photos libraries into one. Use advanced search to find photos across all connected libraries simultaneously by keyword, date, or other criteria. Batch-edit metadata (titles, captions, keywords, dates) across multiple selected photos at once. Export photos or entire albums using PowerPhotos's advanced export options when you need copies outside the Photos app.
