Archivehouse vs PowerPhotos
PowerPhotos from Fat Cat Software is the gold standard for working with macOS Photos libraries — merging two libraries, splitting one in half, finding duplicates inside Photos, browsing multiple libraries side-by-side. It's been refined for over a decade. Archivehouse is a younger, narrower tool aimed at one specific job PowerPhotos doesn't focus on: getting iCloud Photos originals out of the Photos ecosystem and onto a file-tree on a disk you own. Here's where they overlap, where they diverge, and which one you actually want.
Dimension-by-dimension
| Dimension | Archivehouse | PowerPhotos | Edge |
|---|---|---|---|
| Primary use case | Export iCloud Photos originals to a folder tree on local disk, external SSD, or NAS. Organized by year/month, deduped, integrity-checked. | Manage Photos libraries inside the Photos ecosystem — merge, split, dedup-in-library, browse multiple libraries. Stays inside .photoslibrary. | |
| iCloud originals | Auto-downloads iCloud-only originals before writing. The full-resolution file is what lands on disk every time. | Reads from a Photos library on disk. Triggering iCloud downloads is possible but indirect — you typically download via Photos.app first, then operate on the local library. | |
| Output format | Individual image and video files in a YYYY/MM/ folder tree you can open in any tool, on any OS, forever. Not a sealed library. | Output is typically a Photos library (.photoslibrary bundle) you open in Photos.app. Designed for users who want to keep using Photos. | |
| Deduplication | SHA-256 dedup across destinations. Byte-identical files share storage. Cross-asset dedup catches the same image re-imported under different asset IDs. | Excellent in-library duplicate finder with side-by-side comparison and metadata-aware matching. Operates inside the Photos library. | |
| Integrity verification | Verify Hashes pass re-reads every archived file and compares against the captured SHA-256. Detects bit rot and silent corruption years after the archive. | No equivalent integrity-check pass for archived files (the focus is library health, not on-disk file rot). | |
| Library management depth | Read-only. Archivehouse never modifies your Photos library — it only reads and exports. | Decade of polish on merging, splitting, browsing multiple libraries, metadata editing, album restoration. Nothing else on macOS comes close. | |
| External drives + NAS | First-class. Security-scoped bookmarks for external SSD or mounted Synology/QNAP/SMB shares. Multi-destination runs (write to both at once). | Supports writing libraries to external volumes, but the output is still a .photoslibrary bundle — not a folder tree designed for non-Photos consumption like Synology Photos or Immich. | |
| Pricing | Free on the Mac App Store. | Paid (one-time license, generously discounted upgrades). Worth every cent for what it does. | |
| Maturity and edge-case handling | New. Tested against happy-path libraries, Live Photos, multiple destinations, iCloud-only originals. | Decade-plus of edge cases handled — corrupt libraries, partial syncs, format migrations across macOS versions, recovery from bad iCloud states. |
Archivehouse advantage · PowerPhotos advantage · roughly equal
Where Archivehouse wins
- Output is plain files, not a library. If you want your archive readable by Synology Photos, Immich, Lightroom, or just Finder, you need individual files in folders. PowerPhotos optimizes for staying inside Photos.app — different goal.
- iCloud originals path is the first-class flow. Most other tools (PowerPhotos included) assume the originals are already local. Archivehouse is designed around the case where they aren't.
- Integrity verification. Re-hashing archived files years later is uniquely valuable for long-term archives. PowerPhotos doesn't optimize for this because it's a library tool, not an archive tool.
- Free. PowerPhotos is great, but if you only need export-to-folder, you're paying for capability you won't use.
Where PowerPhotos wins
- The Photos library tool, period. If you need to merge two iCloud libraries, split a library across two users, or dedup inside the Photos library itself, PowerPhotos is unmatched. There isn't a credible alternative.
- Maturity. Years of handling weird corner cases, weird metadata, weird sync states. If your library has a long, messy history, that experience matters.
- Visual side-by-side browsing. Comparing two libraries or two suspected duplicates with the actual photos visible is something PowerPhotos does beautifully and we don't attempt.
Pick Archivehouse if…
You want your iCloud Photos archive as **plain files on a real disk** — to feed Synology Photos, Immich, a NAS folder, or just Finder. You care about dedup, year/month structure, and long-term integrity. You don't need to keep using Photos.app for these files.

You want to keep using the Photos ecosystem and you need to manage, merge, dedup-in-library, or browse multiple Photos libraries. PowerPhotos is the right tool — buy it, you'll use it for a decade.
Visit PowerPhotos siteThese two aren't competitors so much as adjacent specialists. PowerPhotos perfects the inside-Photos workflow. Archivehouse perfects the get-the-bytes-out workflow. If you're doing both — managing your active library AND maintaining a long-term file archive — owning both is the answer.
