Professional RAW Photo Development and Processing
RawTherapee is a powerful, cross-platform RAW photo processing application designed for photographers who demand professional-grade editing capabilities without the hefty price tag of commercial software.
Supports virtually all camera RAW formats with multiple demosaicing algorithms (AMaZE, DCB, LMMSE) for optimal image quality and detail extraction from RAW files.
All editing adjustments are stored in sidecar files, preserving original RAW data integrity and allowing unlimited revision of processing decisions without quality loss.
Full support for ICC profiles, camera-specific color profiles, and multiple color spaces with advanced color grading tools including split-toning and HSV curves.
Edge-preserving noise reduction for luminance and chrominance, plus professional sharpening tools including unsharp mask and RL deconvolution for crisp, artifact-free results.
Yes, RawTherapee is completely free and open-source software released under the GPL license. There are no subscription fees, hidden costs, or premium versions. You can use it for personal and commercial purposes without any restrictions.
RawTherapee supports virtually all camera RAW formats including Canon (CR2, CR3), Nikon (NEF, NRW), Sony (ARW, SRF), Fujifilm (RAF), Olympus (ORF), Panasonic (RW2), Pentax (PEF, DNG), Leica (DNG, RWL), and over 100 additional formats through the integrated dcraw library. The software is regularly updated to support new camera models.
RawTherapee offers comparable RAW processing quality to Lightroom and is completely free with no subscription required. While Lightroom has more polished integration with catalog management and cloud features, RawTherapee excels in offering more advanced processing controls and demosaicing options. The main trade-offs are RawTherapee's steeper learning curve and lack of built-in photo management versus Lightroom's subscription cost.
