ImageIntact vs Pho

ImageIntact is a free macOS photo-backup app for photographers. It copies RAW, JPEG, TIFF, DNG, and other image formats to up to four drives simultaneously, with filters for RAW-only, JPEG-only, or all-image backups. Every file copy is checked with a SHA-256 checksum, and suspicious files are quarantined rather than deleted. The app is designed to fit Lightroom, Capture One, and existing folder structures. For NAS and other network volumes, the project describes enhanced data integrity and timeout protection. ImageIntact has no telemetry or cloud requirements, and logs shared for support can be anonymized. Help is available in the app, through GitHub issue reports, or in GitHub Discussions. It requires macOS 14.0 or later and supports Intel and Apple Silicon Macs. The MIT-licensed app is downloaded from GitHub Releases by installing its DMG in Applications. The Free plan costs nothing, is billed Free and always will be, and supports up to four backup destinations.

Pho is a photo backup and gallery app that syncs mobile camera-roll images to storage chosen by the user. It uploads original-quality photos in the background and displays local and remote images together in a timeline with pinch-to-zoom and full-screen viewing. Listed storage includes SMB, WebDAV, NFS, Google Drive, Baidu Netdisk, and S3-compatible services such as AWS S3, Backblaze B2, Cloudflare R2, and MinIO. The sync engine is built into the app, so Pho says no separate Docker container, database, or reverse proxy is needed. Photos go directly to user-controlled storage rather than through Pho’s servers; the maker also says it has no central database, analytics pipeline, or ads. Files use a date-based directory structure that can be browsed with a file manager. The free tier provides a local gallery and basic cloud sync for personal use. Pro adds AES-256 encryption, custom sync filters, multi-threaded sync, multiple directory structures, theme colors, a Release Space tool, and priority support. The annual Pro plan is $19.99 a year.
