Color and tone controls

  • Adjust exposure, white balance, contrast, and saturation.

  • Fine-tune colors with an eight-band color mixer and Point Color selections.

  • Shape tones with luminance and RGB curves, color grading wheels, and sigmoid tone mapping.



Local adjustments

  • Create brush, linear gradient, radial gradient, and shape masks.

  • Select subjects, skies, and objects with on-device AI masking.

  • Apply independent adjustments and creative effects to masked areas.



RAW development and export

  • Support for RAW files from many camera manufacturers, including DNG and Fujifilm X-Trans.

  • Advanced demosaicing, highlight recovery, and Lensfun lens corrections.

  • Export finished photos to Android's media library, including JPEG and lossless JPEG XL.



Non-Destructive
Edits are non-destructive and saved in lightweight .calibraw sidecar files, so you can revisit your adjustments without changing the original photo.

Photo processing runs locally on your device. AI masking requires an initial model download; once installed, the models run locally. (AI models may not work on lower end devices)

CalibRaw is licensed under the GNU General Public License v3.0 or later.
