digiKam
FreeManaging a hundred thousand photos, entirely offline, nothing uploaded
Professional photo library management from the KDE community. Handle large collections, read and process RAW files, group photos automatically by recognized faces, browse by location on a map, batch rename and convert, and maintain tags and ratings. Everything runs locally with no account and no uploads.
Why we picked it
Photo management has an awkward gap: phone galleries and services like Google Photos are convenient but require uploading; Lightroom is the industry standard but bills monthly; and among free local options, most are viewers that collapse under tens of thousands of images.
digiKam fills that gap. Maintained by the KDE community for two decades, GPL-2.0, positioned as offline professional photo management — it manages a library, not a folder.
Core capabilities:
- Large libraries hold up. Photos are indexed in a database (SQLite or MySQL), so collections beyond a hundred thousand images still filter and search quickly. Ordinary viewers cannot do this.
- Complete RAW support via libraw, reading essentially every camera's RAW format, with a built-in editor for exposure, white balance and lens correction (deeper work goes to darktable or RawTherapee, which digiKam can launch directly).
- Face recognition running locally: faces are detected and clustered, and once named the whole library becomes searchable by person. The photos never leave your machine, which is the fundamental difference from cloud galleries.
- Map view placing GPS-tagged photos geographically, with manual geotagging available.
- Metadata management: read and write EXIF, IPTC and XMP, shift capture times in bulk when the camera clock was wrong, batch rename, and apply copyright information across a set.
- Tags, ratings and color labels combined with advanced search for genuinely complex filters.
- Batch queue for format conversion, resizing, watermarking and monochrome conversion.
To be clear about:
- The interface is complex with a real learning curve. It is function-driven engineer aesthetics, with deep menus and an overwhelming number of options; the first launch is disorienting. Start with import, tagging and search only and discover the rest as needed.
- Building the library initially takes time. The first scan, thumbnail generation and face detection across tens of thousands of photos can run for hours. Let it.
- It is not a photo editor. Basic adjustments exist, but serious work belongs in darktable or RawTherapee for RAW, or GIMP and Krita for pixels. Its value is management.
- No cloud sync. Viewing your home library from a phone is Immich's job — the two differ in purpose: digiKam is deep desktop management, Immich is a self-hosted cloud gallery. Plenty of people run both, organizing in digiKam and sharing through Immich.
If you have years of accumulated photographs, shoot RAW, and would rather not hand them to any cloud service, this is the strongest free option available.
