Overview
RawTherapee is a free and open-source desktop application for developing RAW photographs. The project began in 2004, when Gabor Horvath started experimenting with digital camera RAW data and image-processing algorithms.
The software uses a non-destructive workflow. It stores editing instructions in processing profiles rather than changing the original image file. RawTherapee targets photographers who need detailed control over demosaicing, color, exposure, sharpening and export.
Version 5.13 was released on July 26, 2026. Official builds are available for Windows, macOS and Linux, including x86_64 and ARM64 packages for supported systems.
