A fast RAW photo editor for Linux
Lightroom has no Linux app, and neither do most paid culling tools. LightPhotos ships native Linux builds for ARM and x86. It is free, open source, and under 28MB.
What you get
- Fast culling. Rate a shoot from the keyboard with 0–5 stars, pick and reject flags and colour labels, check focus at 100% with Space, and filter by rating, flag or label.
- Non-destructive RAW editing. Exposure, tone, tone curve, white balance, texture, clarity, dehaze, vibrance, a colour mixer, colour grading, sharpening, denoise, vignette, grain, spot removal and Auto Adjust, rendered on the GPU.
- Plain folders. No import and no database. Edits live in a
.lightphotosfolder beside your photos, so they back up and sync with everything else. - Export. JPEG, PNG, 16-bit TIFF, WebP or AVIF at the size you choose, or straight to your own Immich server.
- Private. The desktop app makes no network requests. See Privacy.
How it compares with other Linux tools
Linux already has excellent open-source photo editors. LightPhotos does not try to match their depth. It aims to be the quickest way through a shoot.

- Fujifilm X-Trans files can be browsed and rated from their embedded preview but not yet edited. Nikon High Efficiency NEF, the OM System OM-5 II and Samsung Galaxy DNGs do not open. The full list is on tested cameras.
