Best Free Alternatives to Adobe Lightroom
Updated 3 October 2026 · 3 programs compared
Adobe Lightroom is the favourite tool of many photographers, but on computers it is available only as a subscription. These free, open-source programs cover the same jobs: developing RAW photos without touching the originals, and organising large photo libraries. All three run on Windows, Mac and Linux.
Quick answer
- darktable – the closest free match to Lightroom: library and RAW editing in one.
- RawTherapee – the most precise free RAW developer.
- digiKam – the best free tool for organising large photo libraries.

RawTherapee
Focused on getting the best image quality out of RAW files, with detailed control over colour, sharpening and noise. It uses a simple file browser instead of a catalogue.

- Batch processing
Keep in mind
- No full photo library
- Many technical settings
digiKam
The strongest free photo manager: albums, tags, ratings, maps and offline face recognition for collections of tens of thousands of photos. Pair it with darktable or RawTherapee for advanced editing.
Good

- Maps and metadata tools
Keep in mind
